Stranded when their car gets a flat tire, two sexy girls accept help from two hippies in a dune buggy. After sex to repay the favor, the four team up for a robbery at one of the girl's home, but it goes terribly wrong.

(Based on the video version, 12 minutes shorter than the original)

Two girls come to a halt at a secondary road in a 1970 dark blue Cadillac; The passenger - golden hair, white short sleeved blouse and red trousers with a leather belt - comes out first, looks at the back wheel, and complains, "It's a flat tire!" The driver - with past the shoulders black hair, red top and mini skirt leaving plenty of belly nude, black leather boots, and round-shaped sun glasses - has a look at the car boot, and curses when she finds the spare wheel has also a flat tire.

Just in time, along come two hippies in a yellow Volkswagen Dune Beach Buggy, They offer to give the girls a ride back to their camp, so the girls would pick stuff needed to fix their flat tire, plus have some beer. Instead of talking during the travel to the campsite (by a main road) they only listen to music...

At the camp, they introduce themselves: Joey (John Alderman) chats with Amanda (Kris Kross) who says her full name, and that she is "the scion of Forsythe, Button & Walden", the stockbrokers. Joey asks if that's to impress him, and she says yes. He refuses to tell his family name: "I never had a family - good or bad." She's running away from home. and hates Mrs. Valerie Forsythe, her stepmother who treats her like dirt. Joey shares the sentiment, as his father is a no-good person, too. Joey casually asks if she has some disease, and without waiting for a straight answer, starts grabbing and petting her despite her no and squeals. She opposes some resistance but his wiry arms soon force her down onto a camp bed, for kissing and forced sex.

Meanwhile, Sue (Rene Bond) is talking with Garth (Christopher Geoffries) - blond, showing his arm and chest muscles in a black jacket and jeans - near the buggy by a tree shade. Sue has a similar story, also escaping from home in Mr. Forsythe's car. He compliments her for her «fantastic body» as his large hands try to measure the volume of her breasts. She dissuades him to go on with his fondling.

Joey stops Amanda's objections to sex, and is able to strip down her mini and white slip with no further protest. Joey caresses her nude breasts and does cunnilingus, and she caresses his black hair and moans in pleasure. She keeps her open top, but he strips naked, showing his hairy, tanned body, specially the legs, to make (soft-core) sex to her on the folding camp bed. They keep going, after she mounts him for a while. After a couple of changes, she blows him while he is on his back.

Garth uses a lame excuse to convince Sue to kneel down with him on a rug he brought from the buggy, and tries again to grab her, but she escapes, and runs away through the wood. He runs faster than her, catches her in a bear-hug from behind, and brings her back screaming, to land on the green blanket. He has some difficulty trying to do several things at the same time - unbuckling her belt, exposing her breasts from the sweater, and stopping her squeals. He uses his mouth on her breasts, his left hand on her lips, and finally (at the expense of more squeals) to strip down her trousers. He mounts her, downing his own jeans enough to liberate his penis and start stabbing at her pelvis. But he fails to get an erection. "I'm a freak!" "May be the idea of taking a girl by force just didn't turn you on." Garth pleads with Sue not to tell anyone. She swears she won't even tell Amanda.

While Joey smokes a cigarette in the nude, Amanda puts her slip on and gives details of her family, namely that her older sister Linda is still a virgin because she considers that no man is good enough for her. Amanda makes a proposition to Joey: he could take the house and the car, if he disposed of her family. Joey is not willing to take risks for goods he can't sell easily. Amanda comes with a plan B: she will give him the keys to her house and the location of two safes, so he may rob her daddy's money - $100,000 her stepmother says he has in there. Looking down at him, she sees that the amount got Joey interested, and erect again.

Late in the evening, Amanda is back home with Sue, and is received by her father Jack Forsythe (Chesley Noone) and stepmother Valerie (Marsha Jordan). Joey steps over Garth's' objections to the burglary - he doesn't want any deaths involved - and they proceed to enter by the back door. Joey interrupts the family meeting, yielding a small revolver, and Garth comes holding Linda (Sandy Dempsey), a pretty brunette wearing a flower patterned mini-dress.

The father asks who are these people, and Amanda calmly explains that «they are just business associates» of hers.

Valerie (Marsha Jordan) a platinum blonde in deep v-neck green dress held up by two thin straps, criticizes her daughter-in-law for being snooty, but accepts to go up with Joey and show him the safe.

Mr. Forsythe objects, "But that is not our money!" Valerie counters with, "But it's my skin. You worry about the money!"

Joey gives the pistol to Garth, to keep the order in the living, and takes the stepmother upstairs.

Before showing the safe, Valerie wants to have a little talk, sitting on the couple's bed. She insinuates that Amanda is not to be trusted and that he could leave her US$25,000 and asks for his protection against the girl, "who hates my guts!" In a minute, the green negligee gets undone, and the large bed with a red cover is being tested as Joey has sex with the experienced stepmother, who helps him out of his sweater and his white jeans. He takes off her very small white slip. First he mounts her, then she rides him.

In the living room, Amanda is getting impatient: «They sue are taking their time in there!» Mr. Forsythe calms her: «They're probably counting the money.» The man is only worried because of the consequences, because that money belongs to some dangerous people.

Joey and Valerie are back, and he complains the money was not as much as they thought, and splits the money with Garth and Amanda. Garth is happy: "No more buggies for us, ah, Joey?" Then they leave, Joey eager to buy a car less showing then the Cadillac.

In their bedroom, neither Forsythe nor Valerie are able to sleep.

Joey returns with a sad face, interrupting the sad dialogue between the couple He shouts that the money is counterfeit, Monopoly money, and the Forsythes should have known it! Valerie seems surprised, and Jack confesses the money had been held by him for gangster connections, to be passed in the race tracks. Joey takes the couple downstairs at gun point - Valerie in a light blue, see-through negligee, and Forsythe in his white briefs.

When Joey enters the living, Linda is tied-up, spreadeagled on a rug, on a table, and her nude body is covered by a thin yellow blanket - on a table covered by a panther-skin rug. Amanda is stripped naked except for her boots, and is preparing to end the virginity of Linda. Sue stands back against the wall. Amanda orders Garth to tie her parents' arms with a piece of rope, lifts and throws away the yellow blanket, and gyrates the table top for effect. Linda is not moving, as if drugged, but her head moves sometimes.

Jack objects, "For god's sake, Amanda, she's your own sister!" Amanda asks him if he wants to do the honors instead. She suggests Garth to do it, he demurs, and Joey prompts Garth to do it, mocking his lack of interest.

Amanda picks a long knife from a cupboard, cuts a strap from her stepmother's negligee, exposing a full breast, and then takes her to Valerie's room at knife point.

Sue, realizing the gravity of the situation, takes Garth apart and pleads with him to stop this madness, turning him against Joey.. She tries to convince him that he can «do it». She strips his shirt and her own sweater, they start kissing and fondling each other, he mounts her on the rug-covered floor... Again they lower each other's pants, and with her panting rather squealing, and go through oral sex that excites her. This time he comes inside her - and then comes up with a decision to stop his ten-year-long dependence on Joey. They put their clothes on again, and Sue says they must find Amanda before it's too late.

Joey is going around the house, searching for something of value that can be sold easy.

Sue goes back to the living, where she unties Forsythe who, in turn, unties Linda.

Joey sat down in a room, drinking; he takes his black boots off (for no reason) and uses his flick-blade to cut a painting from its frame.

Garth confronts him, tries to take the flick-blade from him, and they manage to cut the painting instead. Now mad, Joey stands up with the pistol in his left hand and the flick-blade in his right. Joey commands Garth to go outside, and they go.

Jack Forsythe tells Sue that he has a shot-gun in the closet, passes the closet without taking the weapon and goes to his room to put a pair of trousers on, and then - always in a run - returns to the same corridor to take the weapon from its hiding.

It's already morning...

By the swimming pool, Garth pleads with Joey not to kill him, but he pulls the trigger, two, three times - but the gun is empty. He punches Garth who falls into the pool. Garth screams twice, "I can't swim!" Joey obliges him by jumping into the pool, and hitting him on the head with the colt of the revolver, to help him drown faster. However, Garth fights back for a while, until Joey strangles him inside the pool.

Joey gets out of the pool dripping wet, but Forsythe is waiting for him at gun point. "Now you listen good. (...) We're going to Valerie's bedroom and you're gonna coax Amanda out of there. I don't care what you tell her. Tell her the police are outside, anything... but you get her out of there quickly, because my wife's life depends on it. And so does yours" "Okay, Daddy. You got the upper hand. Let's go get your daughter." Joey jumps him, but Forsythe shoots him point blank in the chest. Now there are two corpses in the pool. Forsythe returns inside, slowly.

From the opposite end of the corridor, Amanda comes to him, nude and without boots, her body covered in blood from head to foot, and yielding a big knife in her hand. "Hello, Daddy. She'll never come between us again. I've just put Linda to sleep, so now it's just the two of us. Just like it should be. Daddy, I'm so happy. I love you so much." Her father rearms the shotgun in haste, and shoots her point blank. (Freeze frame on a close up of Amanda yielding the knife.)
