Season 1

During a scientific expedition in the South Pacific, marine biologist Nazareth Vivas and the Pentokontors crew discover a mysterious signal in the ocean. As they investigate, they are attacked by pirates searching for a legendary emerald. Amid betrayals, hidden secrets, and a past that resurfaces, survival becomes their only mission.

After the pirate attack, the Pentokontors crew struggles to survive on a mysterious island. While Máximo and his team uncover an abandoned Russian military base, Nazareth and Jota find signs of an unknown creature in the ocean. With sabotage, hidden threats, and danger lurking in the darkness, the group faces an uncertain fate.

As Ray fights for his life after a mysterious poisoning, Máximo and his team discover that the island hides Soviet secrets and remnants of the MIR station. Meanwhile, Nazareth and Jota stumble upon a nest of unknown creatures, and América steals the emerald from the chest. With food supplies dwindling and trust fading, the group’s survival hangs by a thread.

Trapped in the depths, Mónica and Jota run out of oxygen. Nazareth risks her life to free them while, in the base, Sonia and Nazareth discover that Ray’s body is undergoing an unprecedented mutation. Survival becomes even more difficult as América and Marco attempt to escape, and a mysterious voice interrupts their radio, shattering their last hope of rescue.

Ray's body mysteriously disappears, causing panic in the base. While the group debates whether he is dead or still alive, security footage reveals the shocking truth: Ray got up on his own and vanished into the darkness. With tension at its peak and growing uncertainty about what is happening on the island, the fight for survival becomes even more terrifying.

Smugglers arrive on the island demanding the emerald, triggering a violent confrontation. América reveals she hid the stone, but when she tries to retrieve it, she discovers it is gone. Meanwhile, Nazareth leads Carlos Mendoza and his group through the tunnels, but something lurks in the darkness—a terrifying creature attacks them mercilessly. The battle for control of the island has begun.
