A young woman mourning the sudden loss of her lover becomes embroiled in the world of espionage when she discovers a dead body on the overnight train she is taking. No sooner has she reported the body missing than the man she thought murdered is found to be still alive, and Helen is left pondering her own sanity. An Australian, Bob, seems to want to believe her story, but remains sceptical until Helen once again spots the body in a compartment. The two then pair up to try and determine who the murderer of the man was and, more importantly, why someone is now impersonating him.
