Build a movie plot around this: Who does the policeman say Eddie is really? Eddie Riccardi, gangster
The answer to this question is:
After sustaining a head wound in combat, decorated World War II veteran Eddie Rice (John Payne) is treated at a San Francisco military hospital for a permanent form of amnesia. This leaves him with no knowledge of his life, family and friends prior to his enlistment, a void that the army intelligence unit was unable to fill as they couldn't find any information about him, other than the fact he enlisted in Los Angeles. Doctors tell him that no medical cure exists for his case, but that if he returns to Los Angeles he might run into people who know him and could help him fill in the blanks. Rice follows this advice and he promptly runs into people who recognize him. However, he is recognized not as Eddie Rice, but as Eddie Riccardi, a dangerous gangster gone missing, whose past behavior generates mistrust among the police and all those who knew him in the past. Furthermore, ruthless crime boss Vince Alexander (Sonny Tufts), who was betrayed by Eddie before he left the town, is now out for revenge.
