A crew member is feared lost overboard, and as hours pass with no trace, the Estrella Polar must decide when to end the search and continue their mission. A lighthouse teddy bear identical to one aboard raises suspicion of a strange connection. To cope with tension and worry, the crew holds a boxing tournament for distraction.
