Going Down (1982)

Middle-class Karli, alcoholic Jane, unemployed Jackie, and square Ellen are four friends living together and barely scraping by in suburban Sydney. But when Karli’s father offers her a little money and a one-way ticket to New York, she finally sees a way out of her dead-end life—that is, until the money goes missing, kickstarting a final night out on the town that none of them will ever forget.
