A young woman goes searching for her missing artist father. Her journey takes her to a strange Californian seaside town governed by a mysterious undead cult.

Separation concerns the inner life of a woman during a period of breakdown – marital, and possibly mental. Her past and (possible?) future are revealed through a fragmented but brilliantly achieved and often humorous narrative, in which dreams and desires are as real as the ‘swinging’ London (complete with Procul Harum music and Mark Boyle light show) of the film’s setting.
