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 escapees Krug Stillo and Fred 'Weasel' Podowski are hidden in a hideout with their partners Sadie (Jeramie Rain) and Krug's addicted son Junior Stillo (Marc Sheffler) after killing two guards and one shepherd in their runaway. The two girls seek marijuana near the theater and meet Junior that offers some Colombian grass to them. They go to his apartment 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 shots Mari after humiliating and raping them. They 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 tells her husband and they plot a scheme to revenge the death of their princess.
