A skeleton substitute crew of fish-gutting guys led by Tommi, who just got back in the business, have to work the day before the big fishermen ball. They have to gut/slay everything that is brought in if they themselves want to make it to the festivities, and it seems like the fishermen are bringing in every fish in the whole damn ocean. It doesn't help that the most experienced member of the team is hung over like hell, and the boss was smart enough to book himself a day off and is already gone partying. They will need all the help they can get, even from people they can't stand. They might even need help from above, or a 'Slay Masters' myth.
