After killing and cannibalizing several men and being found unfit for trial, Regina Stevens desperately tried to convince her psychiatric caregivers that she wasn't mentally ill, but was in fact slowly becoming a real life zombie.

In the middle of the desert, a solipsistic Japanese-American woman, along with her elderly and paralysed friend Barbara, runs the Desert Rose Cafe. Things liven up with the arrival of a mafia henchman (whose boss is hiding out at a nearby ranch), a battered Japanse man (who turns out to be a terrific chef, but who also triggers Barbara's memories of internment during WWII), and an attack on the mob boss' camp.
