Hiroshi Saitô's screenplay was reworked by Ann Cherkis to take place in America.
Hannah, the mom (Lili Taylor - "Six Feet Under") and her daughter Sam(Olivia Thirlby - Juno) are in a car accident and through some magic the soul of the mother is transferred to the daughter.
You can imagine the hilarity as Sam, who is now Hannah, but looks like Sam, returns to school as Sam (she is 16) and discovers that her daughter is smoking pot and having sex. Or, when she pops into her husband's office and sees him flirting with her guidance counselor.
Her husband/father (David Duchovny) doesn't know what to feel. He hers his wife, but sees his daughter. Now, that is messed up.
Thirlby was amazing in a dual role.
The ending was messed up.
