The "panic" of the title refers to a temporary shortage of heroin on the streets. This scarcity drives the local addicts to extreme measures, exposing the desperation, betrayal, and decay of moral boundaries that accompany severe dependency. A Masterclass in Cinematography and Direction

Kitty Winn, as Helen, is equally devastating. She won the Best Actress award at the Cannes Film Festival for this role, yet she remains one of the forgotten greats of New Hollywood. Her Helen moves from wide-eyed hope to hollow-eyed exhaustion with a subtlety that makes the transformation feel inevitable, not dramatic.
