While casing a bank he intends to rob, tough gangster Leo L'Americano (Robert Beatty) discovers that Antonio Pellegrini (Robert Beatty), a meek and mild clerk in the bank, is his exact double. Leo kidnaps Antonio and robs the bank, making certain there are plenty of witnesses to testify that Antonio was the bank robber. But Leo hadn't accounted for the involvement of Antonio's wife Dorothy (Jean Kent).
