The Head (Seasons 1–3)

The Head (2020) is a Spanish-produced thriller series you can watch online on iFILM — a whodunit set at the Polaris VI Antarctic research station during six months of unbroken polar darkness.

When the sun returns and the main team flies back in spring, several of the Winterers who stayed behind are dead, and the station's lead biologist has vanished. His wife Anita (Katharine O'Donnelly) is the only survivor who remembers anything — but her account doesn't hold together cleanly. Investigator Johan Berg (Alexander Willaume) works through a closed-room scenario with no exits: the suspect pool is small, the isolation was extreme, and everyone's behavior during the long dark is worth questioning.

Álvaro Morte (Money Heist), Tomohisa Yamashita, and John Lynch headline the international cast. Director Jorge Dorado keeps the tension methodical rather than visceral — the horror here is the logic of who could have done it and why. Stream The Head (2020) online on iFILM.
