A careless prank leads to a feud between two of the veteran captains.

It's week four of the North Atlantic bluefin tuna season and Captain Paul Hebert fights for his first tuna of the season. After days of nothing to show but pulled hooks and sharks, tension mounts on the Kelly Ann. Captain Greg Chorebanian and first mate Greg Gibbs of the harpoon boat Kristiana steam into Gloucester on a mission: to kick rival Captain Hollywood's butt. But they're at a disadvantage without a pilot to guide them to the tuna like Hollywood has. Yet, Hollywood's pilot, Mark Brochu, can't help him throw the harpoon and land a fish.
