Plot
Adventurer Al Colby is persuaded by Anna Luz and her antiquities-collector husband Thomas Berrien to help them smuggle a parcel into Mexico where its true value can be ascertained. Warned that a man named Jefferson, who is traveling on the same freighter, might try to steal the parcel, Colby forms a partnership with Jefferson following Berrien's fatal heart attack aboard the ship. Jefferson betrays and shoots Colby, but Colby saves himself and the rare documents in time. They will be returned to a museum while he and Anna can enjoy a $25,000 reward.
