The Swarm

Scientist Charlie Wagner discovers a phenomenon at an outpost in the Shetland Islands that fascinates Professor Lehmann. Meanwhile, abnormal behaviour of whales off the coast of Vancouver Island worries cetologist Leon Anawak.

As whales attack tourists in Canada and lobsters are turned deadly in France, a scientist discovers aggressive worms multiplying at speed.

Venice sees an unprecedented plague of jellyfish, while in Canada, researcher Anawak is getting to the bottom of whale attacks.

Cécile recommends stopping fishing off the coast and warning the population against using tap water, while the worms are investigated more closely.

When Rahim and Charlie report a light phenomenon and a sound that Jess has recorded, Johanson travels to Shetland. They receive a warning that a tsunami is heading for the Atlantic coast of northern Europe and Shetland.

Johanson suspects that an unknown marine intelligence, which he calls Yrr, is behind all the results. He wants to contact the life form with a research mission and therefore asks the billionaire and entrepreneur Aito Mifune for help.
