That strategically absurd but actual event sets the scene for a compelling tale of innocence, survival, and honor. A young student has been forced into the Imperial German Navy because of his language translation skills.

After enduring horrible conditions onboard the U-boat, the young man risks everything to escape, swimming ashore to the safety of America. However, he finds himself facing poisonous anti-German sentiment and the rabid ambitions of a fanatical gang of vigilantes. His survival depends on the actions of a few honorable menmembers of the local coastal life-saving service and two journalists covering the resulting huge news story. A crewman off the hated and feared attack U-boat has come ashore!
