Part 3/7:
As the submarine crew settles into their submerged routine, rumors begin to swirl about the nature of their rescued companions, especially surrounding Schillings, one of the survivors who is suspected of being a German spy. Tensions boil over into conflict when Clare tries to protect him, leading Bryce to impose strict disciplinary measures that include her confinement. The crew quickly turns inward, becoming increasingly paranoid about potential sabotage.
Amid the psychological turmoil, odd occurrences begin to plague the submarine. After a record player mysteriously activates, drawing attention to their location, the crew suffers a violent attack from the German ship. As chaos ensues, lives are lost, and accusations fly, suspicion solidly entrenches itself in the minds of the sailors.
