He agrees to take the six richest off the ship but is sickened by the distress of the rest and tells the captain to put them ashore on an isolated island.

Ingrid agrees to go with Alexander to the island where the Chalcis is lying, and they are sickened to find all the refugees locked in the hold by the captain and dead.

When Alexander's drugs arrive, concealed in a schooner, they are lifted by Mrs Birk, who is not a cop but a dealer, and hidden in the wreck of the Chalcis.

In an ending that was in accord with the Motion Picture Production Code, police launches pursue them and shoot Alexander dead.
