If It's Tuesday, It's Murder (Season 1)

If It's Tuesday, It's Murder (Si es martes, es asesinato, 2026) is a Spanish comedy-mystery you can watch online on iFILM. A mismatched group of tourists lands in Lisbon for a week of guided sightseeing, only to find one of their own dead by the first morning.

What follows is nowhere in the travel brochure. The police are an ocean away, the guide is sweating, the coach rolls on to the next stop — and the killer is almost certainly buckled into a seat nearby. Someone on this trip lied about why they came. Álex García and Inma Cuesta headline a busload of suspects, each carrying a secret and an alibi that doesn't quite hold.

Directed by Salvador Calvo and Abigail Schaaff, the series folds a cozy locked-group whodunit into a comedy of manners set against postcard Lisbon. It's for viewers who like their detective stories to wink rather than terrify, and who enjoy spotting the culprit a beat before the characters do.
