Set during the Korean War, the film follows Sergeant Paul Ryker, an American soldier accused of desertion and collaboration with the enemy. Captured by Communist forces, he returns to his own lines under mysterious circumstances, leading to doubts about his loyalty. The military swiftly charges him with treason after evidence emerges suggesting he was complicit in the Cold War enemy’s plans. His estranged wife, Ann, is convinced of his innocence and becomes his steadfast supporter despite the damning evidence. Driven by her belief in Ryker, she seeks aid from his military defense attorney, Captain David Young.

Captain Young is initially reluctant to take on the case, overwhelmed by the seemingly insurmountable proof against Ryker. However, as he delves deeper into the circumstances surrounding Ryker’s capture and supposed betrayal, he begins to uncover inconsistencies that challenge the assumptions of guilt. Young is thrust into a race against time to gather enough evidence that could sway the court-martial before an execution sentence is passed. As tensions rise and loyalties are tested, Young finds himself not only fighting to vindicate Ryker but also navigating a complex web of military and political interests that have a vested interest in seeing Ryker convicted. The narrative builds a suspenseful atmosphere as it revolves around the unfolding courtroom drama and Ryker's desperate fight for justice.
