Coming out from jail, Lucas has decided to change his life and behave like a good citizen. But when he is taken hostage in a bank by a hare-brained robber, no cops can believe he is not part of the action.
On his first day after being released from jail for 14 armed bank robberies, Lucas finds himself caught up in someone else's robbery. Perry has decided to hold up the local bank to raise money so that he can keep his daughter, Meg, and get her the treatment she needs. Dugan, a detective, assumes Lucas helped plan the robbery, and hence Lucas, Perry and Meg become three fugitives.
A shipful of fugitives from justice pulls up on a Pacific Island where there are no extradition laws. The island is a magnet for the scum of the earth, as well as a few honest guys who were framed. Into this den of iniquity swims socialite Dorothy Sebastian, who jumped off a yacht after apparently murdering her lecherous host. To remain on the Island, Sebastian is told that she must pay $5,000 to head honcho Fred Kohler -- and if she hasn't got the money, it is implied, there are other methods of collection.
