In 2006, Jess, Alice, Frankie and Blair bond during their first year of college. A decade later they reunite as Jess, now an aspiring politician, is about to marry her boyfriend Peter. Alice decides that the four should spend the weekend in Miami partying. They are also joined by Pippa, Jess's friend from her semester abroad in Australia. Alice, who considers herself to be Jess's best friend, is immediately jealous of Pippa.
The friends get high on cocaine and party at a club before deciding to hire a male stripper. At the vacation house, he makes Jess uncomfortable with his rough talk. Alice becomes aroused and jumps on him; the stripper is knocked to the floor and dies after striking his head on the fireplace. Before they decide what to do, Jess takes a call from Peter and mentions that her friends hired a stripper, and she is confused. Peter thinks that she is leaving him and becomes distraught. His friends tell him that he should drive down to Miami to win her back.
The friends purchase a burner phone to call Blair's lawyer uncle. After telling them they moved the body, he tells them they could face up to fifteen years in prison unless the body is never found. Pippa volunteers to pilot a jet ski out to the ocean and dump the body. After doing so, they think the neighbors' security camera caught them on tape, and send Blair to seduce them for the footage, only to discover the cameras don't work. By this point, the body has washed up back on the shore and they must come up with a new plan to dispose of it.
A uniformed police officer knocks on their door and Frankie knocks him out after he gropes her, only for them to realize he was the stripper they had hired, leaving them to wonder who was killed. They try to dispose of the body again after stealing the stripper's car, only to return defeated after causing the car to crash. Then, when Alice finds out Jess invited Frankie and Blair to a bridal shower over her, Jess berates her for her obsessive clinginess and storms off to prepare for the consequences.
At this point, two plainclothes police officers arrive and tell the women they are not in trouble as the man they killed was a violent criminal who had been on the run from the police. As they interrogate the women, Pippa sees on the TV that the "police" are actually accomplices of the dead man, who had double-crossed them during a heist of valuable diamonds. The thieves realize that they have been caught and tie their captives up, threatening to shoot them.
While preparing to surrender, Jess finds a letter from Alice revealing that she staged the party so that she could show the pictures to her mother, who is implied to have dementia. She exits the bathroom to find the criminals holding the women and the stripper captive as one searches the house for the diamonds. She subdues him using hairspray and handcuffs and fights off the other one as he prepares to kill Blair. After Alice shoots the second captor, the first escapes but is run over and killed by Peter, high on the drugs he took to keep him awake on his road trip to Miami.
Jess reaffirms that she wants to marry Peter and they do it that weekend at a foam party with their friends. The girls have been pardoned for their act in eliminating the thieves. Jess wins her campaign. Frankie and Blair reunite as a couple and Alice hooks up with Scotty, the police officer stripper from the bachelorette party.
At Jess’s victory party, Pippa sings lyrics that allude to the evening. Afterwards, Alice finds the stolen diamonds stashed in a box of naughty pasta from the bachelorette party.
