Seven Miles From Alcatraz

Alcatraz inmates Champ and Jimbo, who were gangsters on the outside, learn about the attack on Pearl Harbor and get the idea that the island prison they call home is sure to be the next attack site. They break out of jail and make it to a tiny lighthouse isle, where they take the few inhabitants hostage. But when Champ and Jimbo uncover a Nazi plot to take over the lighthouse, the crooks must choose to either flee or stay put and stick up for their country.
