Jack Jesso knows that Gluck wants him out of the syndicate. Still, when Gluck sends him on an errand to find a missing guy named Snell for a shady client of his, Johannes Kator, Jesso doesn't figure it to be anything more than a test. He finds the guy alright - sick and rambling - but Gluck double-crosses him, and tosses Jesso on a Europe-bound steamer with Kator's crew, their orders to kill him. Jesso quickly realizes that he holds the key to a big money deal in Snell's ramblings, information that Kator desperately needs. All he has to do to stay alive is keep Kator interested. It's a simple enough scheme - until Jesso meets Kator's beautiful sister, Renette.
