Marcos, a fisherman from Costa Ayala in Gran Canaria, finds his life turned upside down after discovering 150 kilograms of cocaine floating in the water. Instead of reporting it to the authorities, he teams up with his cousin Dalmacio to sell part of the stash, hoping to make a fortune.

However, their plan quickly spirals out of control when Tacha and El Chino, members of a powerful drug cartel, realize part of their half-ton shipment from Colombia is missing. As the cartel intensifies their search for the lost cocaine, the danger escalates.

At the same time, Inspector Fabelo and his police team receive intel from Madrid about the drug operation and launch a high-stakes investigation to dismantle the criminal network. As the police and cartel race to outmaneuver each other, violence and tension simmer on the island.

Set against the backdrop of Gran Canaria, this gripping thriller explores morality, loyalty, and the dangerous consequences of venturing into the world of drug trafficking.
