Brothers Mike (Adam DeVine) and Dave Stangle (Zac Efron) are alcohol salesmen and view themselves as the life of party at family gatherings. With their sister Jeanie (Sugar Lyn Beard)’s wedding in Hawaii fast approaching, their parents tell them they must bring dates to the wedding to keep the brothers out of trouble. When the brothers protest they are shown a video of what really happened at past family gatherings–they burned down a trailer on the Fourth of July camping trip, threw a girl into the gifts table at a cousin’s wedding, and caused their grandfather to have a heart attack at their grandparents’ 50th wedding anniversary. The brothers agree to be on their best behavior and bring respectable dates to the wedding in order to make their sister happy. Not sure how to go about meeting respectable girls, Mike and Dave decide to take an ad out on Craigslist as an all-expense-paid trip to Hawaii. The ad quickly goes viral and the brothers go on The Wendy Williams Show to advertise themselves. They become discouraged when all the women (and one man) they meet are not respectable and are only interested in the free trip.
