The series kicks off with the celebration of the five young protagonists making it to the final of the most important rowing championship of their lives, when they accidentally run over a young woman. Their idyllic summer takes a dark turn the moment they decide to dump the body in the sea and make a pact of silence so that nothing and no one stands in their way to victory. But when the Ertzaintza [the Basque police] gets on the trail of the disappearance, the pressure and guilt begin to escalate within the group to unexpected levels.
