In the end of the 60's or in the beginning of the 70's, Rich Cooper (Tobey Maguire) goes with his mother Rebecka (the gorgeous and sexy Kate Capshaw) to a crazy party, where Janis Joplin and other stranger guests are present. He gets a bootleg tape of his idol Bob Dylan from the host (Kiefer Sutherland), a kiss from a beautiful girl he met in the party, Maya (Uma Thurman) and a news in the end: that night, his father had left his mother. Mother takes her teenage son to a party, to make sure he will not be at home when father leaves the family for good.
