Tuesdays (9:00-10:00 p.m. ET) on The CW


Around the world, strange happenings, borne out of the oceans: Whales destroy boats, deep sea crabs attack beaches, mussels block container ships. An unknown ice worm destabilizes continental slopes and triggers tsunamis. A deadly pathogen spreads into the drinking water.


Across the globe, lives are increasingly imperiled, the situation worsening by the day—and yet, nobody can draw a connection between the seemingly random attacks. Except for a group of scientists who come together through their shared sense that something bigger is at play: an intelligent life force, dwelling in the deep—capable of manipulating the ocean, and everything that resides in it. A being which has borne witness to our destruction of the seas and has decided to drive us to extinction. But hardly anyone believes their findings. And so, the group are forced to undertake a life-threatening mission, tracking the intelligent life force within the Arctic Ocean. It is a mission they know may claim their lives.


Based on the bestselling novel by Frank Schätzing, THE SWARM is created by executive producer Frank Doelger (“Game of Thrones”), Eric Welbers, Oscar®-nominated producer Marc Huffam (The Martian, Saving Private Ryan) and Ute Leonhardt (“Killing Eve”).
