Well Go USA has debuted the first trailer and poster for The Thieves, director Dong-hun Choi's Korean blockbuster that debuts stateside this weekend. Jung-Jae Lee, Hye-su Kim, Gianna Jun, Soo Hyun Kim, and Hae-suk Kim star as five master thieves who attempt to pull of their biggest score yet: the theft of a 318-karat diamond. Take a look at the one-sheet and footage from the highest-grossing Korean movie of all time.

It's the score of their lives - if they can pull it off. Five thieves at the top of their game, and the crew is assembling for their biggest job yet. Popie (Jung-Jae Lee) is the muscle and brains; Pepsee (Hye-su Kim) is the safecracker. Yenicall (Gianna Jun) climbs walls, Zampano (Soo Hyun Kim) is the strategy man, and Chewingum (Hae-suk Kim) is the master of disguise.

But this new score - it's hot. Maybe too hot. But who can resist the Tear of The Sun: a 318-carat diamond, worth 20 million dollars, and locked away in a casino.The vault is impenetrable, the location covered in cops, and everyone knows there's no honor among thieves - especially not the crew Macao Park (Yun-seok Kim), Popie's old partner, has forced their team to work with. As they gear up and stroll into the casino with a plan, skills, and a whole lot of nerve, they quickly learn that avoiding the cops may not be their toughest problem. What's Macao Park's real motive? Who will betray them all? And who will walk away with the diamond?
