On the eve of her seventeenth birthday, Mari Collingwood tells her parents that she is going to the concert of underground band Bloodlust in New York with her friend Phyllis Stone. She borrows the family's car and heads with her friend to a dangerous neighborhood in the city. Meanwhile, the sadistic and cruel Krug Stillo and Fred 'Weasel' Podowski escape from prison and are back to a hideout with their partners Sadie (Jeramie Rain) and Krug's addicted son Junior Stillo (Marc Sheffler) after killing two guards and one shepherd dog in their runaway. The two girls seek marijuana near the theater, and meet Junior who offers some Colombian grass if they follow him to his apartment. They do, and are subdued by the criminals that rape Phyllis. On the next morning, they hide the girls in the trunk of their convertible and head to Canada. However, they have a problem with the car's rod and they stop on the road close to Mari's house. When Phyllis tries to escape, the gang stabs her to death and shoots Mari after humiliating and raping them. The gang seek shelter in Mari's home, but during the night, her mother overhears a conversation of the criminals telling that they have killed her daughter. She and her husband plot to overpower the criminals and revenge the death of their princess.
