A desperate lawyer hijacks the Fortuna so that he can take his daughter out of the country and way from his possessive ex-wife.

Lucky finds himself the target of a killer who has a wager with someone that they can kill Lucky.

A mob front man, Rosey, passes on an offer to Lucky to purchase the Fortuna. Lucky refuses to sell, and a series of incidents soon plague the boat: a staged brawl, a ferocious attack dog, and a fake smallpox outbreak.
