Brothers Mike and Dave Stangle are known for their rambunctious behavior, which consistently ruins family gatherings with their rowdy antics. Their reputation precedes them to the extent that, when their younger sister Jeanie announces her upcoming destination wedding in Hawaii, their parents mandate that Mike and Dave must bring respectable dates to the event in the hope of keeping them in line. Eager to find the right companions while also hoping to score a free trip to Hawaii, the brothers heed their parents' wishes and embark on a quest to find suitable partners. They place an ad online, hoping to attract well-behaved women, and their search quickly goes viral, casting a wide net of potential candidates.

Alice and Tatiana, two clever and unpredictable friends, stumble upon the brothers' advertisement. In a bid to secure what they see as a free holiday, they devise a meticulous plan to transform themselves into the seemingly perfect dates the brothers are searching for. With makeovers and a concocted backstory, they present themselves as sophisticated and demure women, fooling Mike and Dave into inviting them to the tropical nuptials. Little do the brothers know that Alice and Tatiana harbor their own brand of wild behavior that rivals—and potentially exceeds—the unruliness the Stangles are known for, which threatens to turn the picturesque wedding into the ultimate chaos.
