Plot

A mother and her son plan a surprise visit to Los Angeles to see her husband/his father. Halfway there they get into a terrible accident in the middle of nowhere and now must fight to survive.

The former hipster singer Sandra quits her career when she has the baby David. Her husband, the also singer Carl, gives the safest car in the world, Monolith, to her. When he travels to Los Angeles, Sandra decides to visit her parents with David. Monolith's artificial intelligence Lilith helps Sandra to drive in a safe way. When Sandra suspects that Carl may be cheating on her in Los Angeles, she decides to head with David to the City of Angels, and gives her cell phone to entertain David, despite Carl's warning that the car may be controlled by the cell phone. Sandra decides to smoke a cigarette, and overrides Lilith's sensors turning the car into manual. Out of the blue, she hits a deer in a shortcut and leaves the car to see the damage. David locks the car using the cell phone turning into the safest mode, the vault mode, and is trapped inside. Now Sandra needs to find a way to save her son.—Claudio Carvalho, Rio de Janeiro, Brazil
