In the final days of the Vietnam War, a remote castle in the Pacific Northwest serves as a mental hospital for troubled soldiers scarred by their experiences. Isolated and all-but-forgotten, the inmates are running the asylum … until Colonel Kane (Stacy Keach) arrives to take over their treatment. Taking a special interest in one of his new patients – former astronaut Billy Cutshaw (Scott Wilson) who inexplicably aborted his mission to the Moon during its final countdown – Kane seeks answers to the mysteries of the breakdown. But as his time in the castle goes on, the riddles in Kane’s own mind reveal themselves in shocking and violent ways.
