The Wildcard crew is just a week away from unloading their catch at the Port of Karumba. After a bumper haul, and with 21 tonnes of fish on board, they're eager to fill the freezer even more to maximize profits when they sell at unload. Captain Bruce makes a bold decision to head for King Hill, a fishing ground known for its risks — especially its sharks.While King Hill promises a potential payoff, it's also notorious for tough conditions. Tensions rise as they set out for the spot, hoping to land a big catch. But the true test comes for one of their best dorymen, 22-weeks pregnant Jess. She faces a gruelling and terrifying fishing trial that pushes her to the limit.Tired and near-defeated by the most aggressive sharks they've seen this season, the crew escape King Hill and steam to a new fishing spot. It's a scramble to hit their $65,000 target before the unload in Karumba, which is now only a few days away. But just as their luck begins to improve, a shock accident forces Prue to confront the perils of parenting at sea.
