Zero Avenue (1969) on Netflix

Joshua, a reluctant immortal, plans to end his life on his birthday, with the help of Veronica, a prostitute, before his father, the Devil, can kill her.

Joshua wants a special birthday. So, he hires Veronica to fulfill his wish of domination. Fetish is her specialty; for the right price she's up for anything. As the role-play progresses, though, things get out of hand and Joshua's health is compromised. With a heart bigger than her instincts, Veronica sticks around and helps him get back on the mend. In doing so, the dynamic shifts and we find out the real reason Joshua wants Veronica - He is an immortal searching for his mother - and he's convinced she lives inside Veronica, reincarnated and ready to be set free. Equal parts comedy, horror and family drama, Zero Avenue is a morbid meet-cute dancing on the edge of hysteria. Joshua and Veronica take us on a wildly inventive encounter where they trick, drug, and flirt with each other, ending up paralyzed, in suitcases, or roller-skating into insanity - all the while, falling in love (and covered in blood). Dialogue-driven with quick-witted characters, ZERO AVENUE is a mash-up of comedy and horror, exploring a thoughtful meditation on the dangers of family, new connections - and the unknown.
