Full Steam Ahead, a propaganda film sponsored by the German military, was produced in 1933 under the direction of Carl Froelich. Two shipyards compete to build the engine room for a new destroyer flotilla. Ferdinand Wölfel, chief designer at the Bodenhardt shipyard, hopes that winning the contract will also win him Jutta, the boss's daughter. However, Jutta loves Axel Gröning, who is promoted to commander after rescuing the crew of a stranded fishing boat with his patrol boat.
