A very tropical Moby Dick! During the mid seventies a shark had Acapulco in panic. Just before the spring break with the menace of lossing all tourism for the holidays Hilario Martínez, better known as "Long Dog", decides to hunt the animal. He organizes a picnic at the beach where all the family and friends are invited. They all came well equiped with beer, food and guitars to pursue the quest. In a completley surreal and hilarious way, at the beat of latin music the epic legend of this anonymous hero is told. This is a true story.
