National Fisherman got an exclusive sneak peak of tomorrow's episode of "Wicked Tuna." In this clip from the May 17 episode “Pineapple Mafia,” Capt. Dave Marciano and his crew on the Falcon put up a wild fight with a massive bluefin. Don't miss the mishap — will it mean a loss or a landing?



The catch clock ticks away as Captain Marciano and the rest of the Falcon crew struggle to land a bluefin that won’t go down without a fight. As the hours slip by, this tuna keeps coming back for another round. The crew finally gets a shot at it around hour eight. But that will they reel it in?

NatGeo's "Wicked Tuna" airs Sunday at 9/8c.
