Original: El secreto del río
When a young boy arrives in a small Mexican village, a profound friendship blossoms with a local kid — and a dark secret seals their bond forever.
Manuel arrives in his grandmother's town to a mixed reception. A sight at the market soon captivates him, while Erik hesitates to open up.
The boys are haunted by eerie visions. Manuel starts school, facing new challenges — and finding solace with the Muxes. A discovery is made at the river.
After lying their way out of a situation with Pau's help, Manuel and Erik skip school in search of the truth, growing closer than ever in the journey.
The case takes an unexpected turn. After a looming loss, Rafaela steps in to protect Manuel, but before long, Manuel must face what he most fears.
Years pass, and a mysterious woman arrives in the town, shocking those who see her and finding herself baffled by the enigma surrounding her old home.
Sicarú confronts her past, while Erik confronts his own feelings. Alejandro welcomes someone new to the town. Pau gets her results.
Pau wonders what's really going between Erik and Sicarú. The Muxes act quickly to shield Emi, who discloses a much darker truth than imagined.
The Muxes spring into action to drive Felipe away. Ana finally hears what really happened to Pedro, but the turmoil in the town is far from over.
