Nico wants to be a famous film director. He's pretty sure if he can make the right movie, and soon, his life will completely change. The catch? His parents are sending him to Puerto Rico for the summer to stay with his iconic, but old-school, Abuela Luciana, and his awesome, but unpredictable cousins. Still, the show must go on.
Until Nico and his cousins awaken a monster. A monster that looks an awful lot like the infamous Chupacabra. And it turns out this isn't a chance encounter. The creature begins stalking them all over Puerto Rico, turning up on every dark corner, sandy beach, and moonlit night. To make matters worse, a shadowy cult enters the chase, intent on capturing them before the Chupacabra can.
Soon they are thrown into an adventure that brings them face-to-face with the ancient Taino people, even more ancient Taino gods, and the mysterious Chupacabra, who is somehow linked to everything. Nico keeps his camera rolling, hoping the epic documentary will catapult him to stardom. But in the end, it's the island's fate that hangs in the balance, as they face down the very gods that created Puerto Rico.
