The film kicks off in a chaotic manner when a robber, disguised as Santa Claus, breaks into the home of Craig and Day-Day in the early hours of Christmas Eve, specifically at 3:37 AM. In a frantic sequence, Craig engages in a struggle with the robber, resulting in a wild scuffle that leaves their apartment in disarray while he desperately tries to rouse Day-Day from his sleep. Unfortunately, the robber escapes, making off with both their Christmas gifts and their rent money. The following morning, the police come by to take a report of the theft.
After the police depart, Mrs. Pearly pays them a visit, delivering an ominous warning: if they don’t pay their overdue rent by the end of the day, she’ll evict them. To escalate matters, she threatens to send her ex-convict son, Damon (who has just recently been released from a lengthy twelve-year prison sentence), to deal with them if they miss the deadline. On the same day, Craig and Day-Day acquire new positions as "Top Flight Security Guards," courtesy of Moly, the manager and owner of a notoriously shabby doughnut shop alongside the shopping center they are tasked with patrolling.
During their shift, they cross paths with Donna and Money Mike, the proprietors of a budding shop named 'Pimps and Hoes'. The shopping center also features a BBQ rib restaurant called 'Bros. BBQ', operated by their fathers, Willie and Elroy. Trouble brews when a couple of baseheads attempt to rob Money Mike’s store, but Craig and Day-Day spring into action and manage to catch the thieves. Money Mike offers them a cash reward, which Craig declines, instead inviting him to his upcoming Christmas party. Meanwhile, Willie and Elroy struggle to manage some misbehaving children; Elroy resorts to using a belt in a fit of rage after one child kicks him.
As fate would have it, after Moly grants Craig and Day-Day a lunch break, they find themselves pursued by a gang of thugs, allegedly the descendants of carolers that Day-Day had earlier chased away from loitering in front of the corner store. Unable to catch Craig and Day-Day, the gang directs their anger at Moly, whom they beat for supposedly concealing the duo. Witnessing this shocking incident prompts Craig and Day-Day to throw away their security uniforms and quit their jobs, leading Moly to promptly “fire” them, wrongly accusing them of slacking off.
As an act of revenge, Willie reports Moly to the Department of Health. That evening, Craig and Day-Day organize a rent party to recover their stolen rent money and maintain their home. Chaos ensues during the party when Money Mike tries to use the bathroom, only to encounter Damon, who attempts to sexually assault him. This is thwarted when Money Mike retaliates by crushing Damon’s testicles with pliers. Damon chases after Money Mike in a fit of rage. Meanwhile, Mrs. Pearly makes a move on Willie while borrowing his bathroom, inciting a confrontation when Craig’s mother, Betty, walks in and intervenes.
In a thrilling turn of events, Craig and Day-Day catch sight of the robber once again and take off in pursuit, navigating through bizarre encounters, including a hilariously unhinged old man, played by Mike Epps, who is armed with a double-barreled shotgun. Their pursuit culminates in success as the robber meets his end when he is run over by Pinky's limousine.
The film wraps up with Craig and Day-Day reclaiming their stolen rent money and Christmas gifts while binding the robber to the roof of his own house. The end credits reveal that Craig and Donna share a romantic moment post-recovery, Damon is still in hot pursuit of Money Mike in the neighborhood, and Ms. Pearly’s attempt to halt the party by calling the police fails miserably when they accept marijuana as a bribe.
