Zoo (Seasons 1–3)

Zoo (2015) is a CBS science-fiction thriller you can watch online on iFILM. Across the planet, animals stop fearing people. Then they start attacking — coordinated, as if following orders.

Renegade zoologist Jackson Oz is the first to sense something wrong, out on an African expedition where the lions behave less like beasts and more like a pack with a plan. Soon the violent outbreaks reach cities worldwide. Oz pulls together a mismatched team — a journalist, a vet, a reporter and a government agent — and they scramble to work out what flipped this switch in nature, while there are still places left for humans to hide. The cast features James Wolk, Kristen Connolly, Nonso Anozie, Nora Arnezeder and Billy Burke.

The series adapts the novel by James Patterson and Michael Ledwidge, built on a lean, gripping premise: what if the enemy isn't a virus or aliens but the entire animal kingdom at once. Each season raises the stakes from scattered attacks to a threat against the whole species. Stream every season of Zoo online on iFILM.
