An English adventure by John Huston starring Humphrey Bogart.
The leader of a crime gang and the owner of land rich in uranium meet with their wives in a port in Italy as they wait for the boat to be ready to leave. The wives get to know each other's husbands and seem to begin a simultaneous affair with these men, switching partners. When the boat leaves, the crime gang and the couples are on board when it sinks.
I liked the plot and thought it was interesting. Apparently, the script was written on a day-to-day basis while filming was taking place. The characters were good and the acting was adequate. There seemed to be something missing though, style. There was none. I'm rating this o.k. because it was mediocre and only slightly interesting.
