The season 21 premiere of Deadliest Catch features a dangerous ammonia leak on Captain Jake Anderson's boat, Titan Explorer, leading to a potential ship abandonment, along with intense rivalries and successful crab hauls in the challenging Alaskan waters, highlighting the perilous life of crab fishermen.
The new season of "Deadliest Catch" follows third-generation fisher Sophie "Bob" Nielsen as she learns the ropes of the family business after inheriting her family's 74-foot wooden hull vessel. The show explores how Nielsen lost both of her parents "in a quick succession." The season chronicles how Alaskan crab prices have reached an all-time high, prompting veteran captains and a wave of newcomers to sail the high seas to earn big bucks quickly. Fishing continues to be a male-dominated industry, but Nielsen is determined to prove herself. The two-hour season premiere of "Deadliest Catch" airs April 18 at 8 p.m.
