Season 4

Who's the Murderer (2016), Season 4 — watch online on iFILM across twenty-seven episodes of celebrities staging a murder and then racing to solve it. Same engine, fresh crimes: one detective against a room full of liars.

Every case opens on a body and a tangle of alibis. The cast claims their suspect roles, walks the scene, pieces the timeline together from scattered clues, and tries to name the killer hiding among friends. This run sharpens the production — denser sets, nastier twists, final votes that stay live to the closing episode. He Jiong runs the table again, and each round sorts the good liars from the sharp readers. Best for anyone who likes a logic puzzle wrapped in loud, playful improv. Stream Who's the Murderer Season 4 online on iFILM.
