January 1942. The Atlantic War has been raging for three years and the losses on both sides are high. Despite the massive expenditure of man and material, the Atlantic still has to be crossed in order to secure the supply chain for the Allied powers. Time and again, convoys with a large number of transport ships are flanked by destroyers in order to bring them safely to their destination. As far as possible, airplanes provide escort. The not so young Ernest Krause was given command of the USS Keeling shortly after the USA entered World War II. The destroyer, nicknamed Greyhound hears is supposed to bring a convoy of 37 Allied ships safely through a five-day period in which air support is interrupted.
Marvel could have had pioneering status: The studio introduced the superhero Black Widow into their film universe early on, but - for whatever reasons - no solo film was made with her, which was the first superhero blockbuster that won over critics and box office after failures like "Supergirl" , "Catwoman" and "Elektra" could have been. The competitor DC succeeded in doing this with “Wonder Woman”.
