Tom Merriam signs on the ship Altair as third officer under Captain Stone. At first things look good, Stone sees Merriam as a younger version of himself and Merriam sees Stone as the first adult to ever treat him as a friend. But after a couple strange deaths of crew members, Merriam begins to think Stone is a psychopathic madman obsessed with authority. He tries to tell others, but no one believes him, and it only makes Stone angry.
