Revolver

“Now, keep your promise.”

Ha Su-young (Jeon Do-yeon), a former detective turned private investigator, takes on a case that pulls her back into the underworld she left behind. Andy (Ji Chang-wook), a fixer with his own reasons to dig, becomes her unlikely partner as they chase a trail of violence and betrayal through Seoul's criminal networks. The investigation tightens around them both, and what Ha Su-young discovers about herself costs her more than she bargained for.
