Indiana Jones and the Sargasso pirates

When Indiana Jones hires a ship to take him to the location of a Viking vessel, he finds himself in the company of an old enemy, a femme fatale on the run, and a con man posing as Indy's brother. When events throw the four of them together on a life boat, they drift into the Sargasso Sea, a ship graveyard inhabited only by wrecks and a band of dangerous pirates.
