As co-captain Mandy begins her own family, starting over in the land of their ancestors becomes an unexpected journey to rediscover a lost legacy.

Whilst fishing for king crabs, Sig discovers a surprise within his gear. Later, he entrusts the 193-foot Stalbas to Jake while he and Mandy pursue a brand new species to create a larger fishing empire.

On the brink of launching a new crab market in Europe, Sig and Mandy go all in on a big change in strategy.

When Jake chases Russian kings far to the North, the Hansens must add a new boat to their Norwegian fleet for a chance at tanking the biomass.

Sig searches for secrets from a fishing legend; when Jake locates relatives, he puts together pieces of his family's past and finds unexpected answers about his own late father; Clark must prove can tank the crab on his own.

After guaranteeing a troll crab delivery backed by king crab, Sig must make good on his deal before the clock runs out. Jake makes peace with his late father's passing while Mandy finds she has an eye for traditional Norwegian cuisine.
