This release combines the hilarious first two entries of the Hangover series, following the exploits and misadventures of a wild pack of friends (Bradley Cooper, Ed Helms, Zach Galifianakis, and Justin Bartha). In 2009's The Hangover, a blowout Las Vegas bachelor party turns into a race against time when three hung-over groomsmen awaken after a night of drunken debauchery to find that the groom (Bartha) has gone missing, and attempt to get him to the alter in time for his wedding. In 2011's The Hangover II, it's Stu's (Helms) turn to tie the knot, and the gang take their mishaps to Thailand for an unforgettable weekend in Bangkok.

For 19 year old Jay, fall should be about school, boys and weekends out at the lake. But after a seemingly innocent sexual encounter, she finds herself plagued by strange visions and the inescapable sense that someone, or something, is following her. Jay and her teenage friends must now find a way to escape the horrors that seem to be only a few steps behind in this critically-acclaimed chiller that Bloody Disgusting calls the scariest movie of 2015.
