Legends (2026) — IQ Score 166/200

Neil Forsyth (Guilt, The Gold) dramatizes the real-life Customs investigators who infiltrated the British and Spanish drug trade in the early 1990s. Steve Coogan plays the team's senior officer, Tom Burke the operator who got closest to a Costa del Sol kingpin, and Hayley Squires the woman who ran the office side.

Forsyth's signature — paring forgotten history down to its propulsive bones — is at full strength across six episodes, and the show is unusually clear-eyed about how undercover work corrodes the officers, not just the targets.
