In June 1942, a German U-boat surfaces off Long Island and puts eight Nazi saboteurs ashore with explosives, forged documents, and cash meant to cripple American war production. This History Hit film reconstructs Operation Pastorius from the landing site to its collapse, using period footage, reenactment-style visuals, and expert commentary to trace how a Coast Guardsman's chance encounter on the beach and one saboteur's decision to turn himself in unraveled the entire plan. J. Edgar Hoover's FBI is shown racing to run down the remaining conspirators before they can strike targets like the Aluminum Company of America and key rail lines. The film lays out the tribunal that followed, the swift executions, and the propaganda value Hoover extracted from a mission that came apart largely through its own agents' incompetence rather than American counterintelligence. It's a compact case study in how ambitious sabotage plans can fail long before they reach their targets, undone by nerves, betrayal, and bad luck.
