On a mysterious island in the Caribbean, a group of criminals led by the cunning and deceitful Juan decides to execute a daring plan to steal a shipment of money from a wealthy businessman. As they prepare to carry out their heist, they stumble upon a strange mystery: a sea creature that is said to lurk in the surrounding waters, with legends that speak of its insatiable hunger for humans and treasures.
However, the complexity of the plan intensifies when the criminals start experiencing a series of strange and terrifying events. Over time, they realize that they have to deal not only with their own distrust and internal rivalries but also with the imminent threat of the creature that seems to be stalking them. As the tension rises, the interactions between the characters become increasingly absurd and comedic, with a touch of horror that adds a unique twist to the mix.
The situation becomes critical when a traitor among them reveals their true intentions, and the group is forced to unite to survive against the threat of the creature and their own betrayals. With a touch of satire and a nod to the pop culture of the time, the characters find themselves embroiled in an adventure that is both a homage to B-horror movies and a parody of them, showing that sometimes, the true monster is not the one that emerges from the water, but the one sitting right next to you.
