Crudely assembled but craftily written, this black-and-white 16-millimeter feature begins as a character comedy and gradually flowers into surreal fantasy and existential drama. An apartment-building elevator stalls between floors, stranding a spooky 26-year-old virgin (writer-director Zeb Haradon) who’s obsessed with anal sex and an alluring born-again Christian (Robin Ballard) who’s rejected the sexual adventurism of her youth. Days and then weeks pass without rescue, yet the two are sustained by a magical bag of groceries that’s refilled every day, leaving them free to chafe against each other and get tangled in their own neuroses. Technically this is a mess, with a laughably fake set and a sound track that seems to have been edited with kindergarten scissors, but the story is eccentric and darkly funny. 95 min.
