A rogue cop goes to unexpected lengths to catch a serial killer in this thriller from Thai filmmaker Kongkiat Komesiri. Lt. Chin (Chatchai Plengpanich) is a police detective with a crooked streak but a real passion to see that justice is done. Chin's latest investigation finds him looking for a killer at large who preys on men frequenting Thailand's booming underground sex trade. When Chin runs short on leads as dismembered bodies keep turning up, he gets a message from Tai (Arak Amornsupasiri), a former colleague doing time for multiple murder. Tai thinks he knows who the killer is, and is willing to find him in exchange for a fifteen day pass. Chin agrees to the deal, and after trolling a number of sex clubs and low-life hangouts, Tai returns to the village where he grew up. As Tai flashes back on memories of a frail boy who was a target for bullies, he pieces together the disturbing story of a maniac on the prowl. Cheun (aka Slice) was an official selection at the 2010 Rotterdam International Film Festival.
