Octonauts: Deep Frontier

**NEW EPISODES EVERY WEDNESDAY AT 08:30 GMT UNTIL MARCH 11TH**

When catastrophic 'accidents' begin plaguing Earth's oceans, the Global Defence Force has no choice but to reactivate their most controversial unit: The Octonauts, an elite underwater special operations team disbanded after a mission went tragically wrong.

Led by Captain Barnacles, a haunted ex-Special Boat Service commander carrying the weight of three lost souls, this crew of military specialists and reformed criminals must navigate more than just crushing depths and hostile waters. Each rescue mission, from collapsing ultra-deep mining platforms to weaponized sea creatures, reveals another piece of a terrifying conspiracy that reaches the highest levels of the GDF itself.

As exotic bioweapons emerge from cancelled black projects and 'natural' disasters strike with surgical precision, the Octonauts discover they're not just saving lives, they're being used as pawns in a game whose stakes threaten all life on Earth. Someone called The Architect is systematically testing weapons capable of reshaping the planet's oceans, and every trail leads back to secrets the team's own members have tried to bury.

In a world where International Rescue handles the headlines, the Octonauts operate in the shadows beneath the waves, where the pressure can kill you in seconds and your allies might be your deadliest enemies. However, when the truth finally surfaces this broken team must overcome their demons and prevent an extinction-level betrayal.

The ocean's depths hide many secrets. Some of them want us dead. All of them are about to surface.

Set in the Greyseal9 Universe.
