Having released a vague plot that makes fans keep wondering what it is all about, "The Hangover Part III" finally clears it up with the release of its new trailer. The video gives out new details as well as extended look which lead fans to a conclusion that the Wolfpack's adventure in the third film is related to Leslie Chow.

The film will put a spotlight on Ken Jeong's Mr. Chow as he is the reason why the Wolfpack travels to Tijuana and ends up in Las Vegas. John Goodman has the boys held captive and demands them to track down Chow, who stole $21 million from him. This is why fans will get to see them busy chasing Chow, who is later seen indulging in cockfighting and other acts of hedonism.

In addition to the video, the Todd Phillips-directed film releases a new poster, which features Bradley Cooper, Zach Galifianakis, and Ed Helms striking a cool pose. Other previously-released posters see Helms struggling to carry Jeong, Cooper with his aviator glasses, and Galifianakis being chased.

Warner Bros. Pictures' film also sees Heather Graham's return as Jade, and features Melissa McCarthy as a newcomer in the cast ensemble. The comedy is slated to hit U.S. theaters on May 24.
