Deadliest Catch

The series follows eight to ten crab fishing boats and their crews throughout two of the dangerous crab fishing seasons, the October king crab (frequently called "red crab" or "red gold" by crew members) season and the January opilio crab ("orange crab", "orange gold", "snow crab", "opies", or, as Northwestern crew member Matt Bradley dubbed them, "Norwegian dollars") season. The show emphasizes the very real danger to the crew on the decks of these boats; situations are just as dangerous for the Discovery Channel camera crews filming them as they are for any other member of the fleet. Each episode has a focus on a story or situation that occurs on one or more boats, with side stories on the backgrounds and particular activities of one or two crew members, in particular the "greenhorns" (rookie crew members) on several boats.
