When George and Betty Cornfield's only son Tommy is killed in combat, their lives are badly affected and the father falls into a deep depression. Out of the blue however, a soldier named Marty turns up on the doorstep claiming to be Tommy's best friend, and re-assures the two grieving parents about their boy's last moments. Marty is so like Tommy in every way that he quickly becomes like their own son, and is even introduced to Tommy's fiancée Sheila. It soon looks as though marriage is inevitable, but Sheila's friend Grace begins to suspect Marty's motives and realises that he is clearly not who he claims to be. As the soldier ingratiates himself deeper and deeper into the Cornfield's lives, Grace becomes ever more alarmed at the possibility that Marty could be genuinely dangerous. For far from being the late boy's best friend, Marty is in reality a deserter with a far more cunning agenda than anyone could have imagined.
