Captain Stone orders that Merriam be restrained, trussed, and placed on his bunk. He then orders first officer Bowns (Ben Bard) to inject him with a sedative. As Bowns leaves Merriam's cabin, he is met by Finn (Skelton Knaggs), who hands him the telegram radioman 'Sparks' Winslow (Edmund Glover) was ordered to send to the Durham Line agent saying that Merriam was not on board. Bowns reads the message without comment, neither of them knowing that the captain is watching. Stone follows Bowns and listens in as he discusses with some other crew members the possibility that Merriam is right about the captain being the murderer. Haunted by the thought that Merriam is right about him, Stone grabs a knife and goes to Merriam's cabin. While the crew on deck sings calypso music, Stone creeps up to Merriam's bed. Just as he is about to plunge the knife into Merriam, Finn bursts into the cabin, also armed with a kife. They fight violently while Merriam watches helplessly. Finn succeeds in stabbing Stone and killing him. In a voiceover, Finn says, 'The boy is safe, and his belief in men and men's essential goodness is secure.' In the final scene, the Altair returns to port at San Pedro. As Merriam leaves ship, he encounters the blind man singing, 'Blow the Man Down.' A woman's voice calls to him and, in silhouette only, a young girl approaches him and introduces herself as Ellen's sister, then she and Merriam walk off together.
