Undercover

Undercover (La infiltrada, 2024) is a Spanish crime thriller you can watch online on iFILM, directed by Arantxa Echevarría and starring Carolina Yuste alongside Luis Tosar. The film is drawn from fact: a twenty-year-old policewoman takes on a false identity and spends eight years embedded with ETA, the armed Basque separatist organisation.

She shares apartments with its leadership, cuts off her family, and builds a second life detail by careful detail — all converging on 1998, when ETA declares a ceasefire that everyone on her side knows is a lie. Tosar plays her handler, the one who tracks every risk and understands exactly what the operation is costing her. Echevarría keeps the register quiet and interior throughout the film's 119 minutes; the tension is pressure, not spectacle.

For viewers who prefer their spy thrillers grounded in the texture of long-term undercover work rather than action set-pieces, this one delivers something rare. Stream Undercover (2024) online on iFILM.
