During World War II, a suspected Japanese spy escapes from a California internment camp. A seven man squad of American soldiers is assembled to track him down before he can reach a makeshift POW camp assembled by fellow enemy soldiers to share information. But tensions mount within the squad when it’s discovered that one of their own harbors a dangerous secret after being released from an experimental brainwashing program. As the men trek deeper into the California landscape and battle a plethora of traps and obstacles, lines begin to blur and it becomes unclear who the real enemy is.
