Rough Night

In 2006, four friends, Jess, Alice, Frankie and Blair, bond during their first year of college. A decade later they reunite as Jess is about to get married to her fiancé 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 in Australia. The friends get high and party at a club and then decide to hire a male stripper. When the stripper arrives at the door, he makes Jess uncomfortable with his rough talk. Alice decides to take a turn and jumps on him, causing them to both fall and the stripper to hit his head on the edge of the fireplace, killing him. 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 takes this to mean that Jess is leaving him and decides to race down to Miami to convince Jess to take him back.

The friends purchase a burner phone and call Blair's uncle, who is a lawyer. After telling them they moved the body, he tells them they could face up to fifteen years in prison unless no body is found. The friends decide to dispose of the body by throwing it into the ocean. After doing so, they realize that their neighbors' security camera caught them on tape and send Blair to seduce them to get the footage only to have her discover the cameras don't work after she has slept with them. By this point, the body has washed up on the shore and they must come up with a new plan to dispose of it.

A police officer knocks on their door and Frankie knocks him out after he gropes her, only for the friends to realize that he was the actual stripper they had ordered, leaving them to wonder who they killed. They use the stripper's car to try to dispose of the body again only to return home defeated after a car accident. Then when Alice finds out Jess invited Frankie and Blair to a bridal shower over her, Jess verbally berates her for her obsessive clinginess and storms off to prepare for the consequences.

At this point, two 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 realizes that the "police" are actually the accomplices of the man they killed. Realizing that they are caught, the men tie up the women and the now-awakened stripper and threaten to shoot them. Jess meanwhile has missed most of the drama due to being upstairs taking a shower in preparation for her mugshot. Realizing what has happened, she manages to subdue one of the captors using hairspray and handcuffs and fights off the other one as he prepares to kill Blair. After Alice successfully shoots the second captor, the first one reappears having freed himself from the toy handcuffs only to be run over when Peter, high on the drugs he took to keep him awake on his roadtrip to Miami, crashes into the front of the house and kills him.

Jess reaffirms that she wants to marry Peter and the two marry that weekend at a foam party with their friends in attendance. Frankie and Blair decide to reunite as a couple and Alice hooks up with Scotty, the police officer stripper that she met at Jess's bachelorette party.

In a mid-credits scene, Pippa sings a song at a function for Jess with lyrics that allude to the evening.

In a post-credits scene begins with Jess and her now-husband, Peter, driving Alice home after a night out. Alice enters her apartment and looks for something to eat. She eventually finds the penis-shaped pasta from earlier in the film in her pantry and decides to cook it. When she pours it into the pan, she discovers that there are diamonds mixed in with the pasta (the same diamonds that the "stripper"/thief stashed in their house for safekeeping before they accidentally killed him).
