Molter says they will leave early on the U-64 and stop for medicine in Belgrana on the way. In Belgrana, Young successfully slips a note to a nurse at the clinic, but von Molter shoots the nurse so there will be no witnesses and finds the note. At sea, a US Navy ship discovers the U-64. Von Molter takes evasive action, but Madeline risks her life to fire a flare, revealing their location, as Young instructed her to do. The US ships fire depth charges. Von Molter shoots debris out the torpedo tube, to make the Americans think they have sunk the submarine. Among the items is a lifejacket, on which Young wrote the coordinates of the planned meeting at sea, where Gurnitz will be handed over. The Americans continue firing depth charges, so von Molter risks everything, taking the U-64 below the maximum safe depth to successfully hide. When the U-64 reaches the meeting point at sea, Von Molter takes Gurnitz over to the other ship, along with Young and Madeline, who are to be killed. As von Molter unwraps his payment, it is revealed to be the life preserver with the location written on it by Young. US Navy men appear, revealing they laid a trap. Von Molter says his submarine has orders to fire on the ship if he is not back in ten minutes. The Navy refuses to allow him to return, so everyone waits a few tense minutes until, just as the U-64 prepares to fire, a squadron of US military planes appears, bombing the U-64, and saving the day. Back in the present, Young argues to the U.S. Attorney that Madeline risked her life to save them all and should not be charged with treason. The U.S. Attorney agrees, allowing Young and Madeline to walk off together, arm in arm.
