The Hangover Part III 2013 R6

Alan Garner's latest mishap with his new pet giraffe gets him in very deep trouble--so deep that his father has a heart attack and dies in the middle of lecturing Alan about owning up to his mistakes. The Wolf Pack reunites at the funeral, and Alan's mother informs them that he has gone off his ADHD medication and is completely out of control. So the four of them stage an intervention and decide to send him to a rehab facility in Arizona. On the way there, their car is rammed off the road by a guy named Marshall. It turns out on the night four years earlier when Alan bought roofies for Doug's bachelor party, he inadvertently stalled a gold heist worth $42 million. Marshall wants it back, and has kidnapped Doug in order to send a message to the Wolf Pack. Their mutual acquaintance Leslie Chow, who made off with half that gold that night, has escaped from a Thai prison and is headed back to North America. But it appears that only Alan knows Mr. Chow's destination. This sends the Wolf Pack to Tijuana, Mexico, then back to Las Vegas. Can he foil the plot, make everything right for the Wolf Pack--and finally meet his dream girl?
