Lucille Ball and Desi Arnaz face a crisis that could end their careers and another that could end their marriage.

When a charming fare named Penny climbs into his cab, Harris, a world-weary taxi driver, finds himself engaged in the only kind of courtship he can have with a passenger -- one that lasts as long as her trip. That is, right up until she disappears from the back seat without a trace. When confusion gives way to reality, he resets his meter and is instantaneously transported back to the moment when she climbed into his cab. He and Penny find themselves trapped in an endlessly looping nighttime cab ride, with only each other for company, and it changes his life forever.

Four estranged friends reunite and spend the night in a remote country house that was once home to a Manson Family like cult. As the night goes on, the strange rituals in the house's past open connections between the past, the present and the subconscious, forcing all the characters to confront their deepest secrets and darkest demons, or be destroyed by them.
