Calvin, portrayed by Marlon Wayans, has just stepped out of prison, only to find that his life has become even more absurd. A shocking twist reveals him to be a little person, which adds a comedic spin as he reconnects with his not-so-bright accomplice, Percy, played by Tracy Morgan. Percy, whose aspirations of becoming a rapper land him in precarious situations, has an audacious plan: secure a diamond from a local jewelry store, promising each of them a reward of $50,000.
Meanwhile, life outside is buzzing in different exciting and humorous ways. At a fancy restaurant, Darryl, portrayed by Shawn Wayans, is in the midst of a discussion with his friend Jimmy, played by David Alan Grier, about timing his decisions wisely, particularly concerning a relationship with Vanessa, played by Kerry Washington. Vanessa surprises Darryl with her promotion, which is soon overshadowed by Darryl's own secret wish for a baby.
As Calvin and Percy hatch their plan, they infiltrate the jewelry store with Calvin cleverly disguised in a duffel bag. Taking a comedic route, Calvin discreetly saws away at the diamond's security while remaining undetected under the table. Chaos ensues when a dog unknowingly leaps into the bag, which later leads to a humorous police chase when security catches wind of the diamond's theft. Calvin cleverly stashes the diamond in a woman’s purse to evade capture.
When the pair discovers Darryl’s aspirations for fatherhood, they concoct an outrageous scheme to disguise Calvin as a baby to reclaim the precious diamond. They hatch a plan where Percy drops off “the baby,” Calvin, at Darryl and Vanessa's home, leading to a series of humorous misadventures that test the couple's tolerance and resolve. The comedic tension boils over when Calvin ends up in the doctor's office, where his apparent “baby” behavior, coupled with reveals such as tattoos and scars, does nothing to quell the couple’s growing suspicion.
As they find themselves grappling with the absurdities of the situation, Calvin experiences a weekend filled with awkwardness and hilarity. The bathing rituals take a comical turn when Darryl, not fully aware of the precariousness of their situation, jumps into the tub, leading to an explosion of laughter and flatulence that leaves Calvin aghast.
Percy's story unfolds as he ventures into a bar controlled by the menacing mob boss Walken, played by Chazz Palminteri, setting up a contract that fuels the rest of the heist. Back at home, the ruse escalates further with the arrival of Darryl and Vanessa's nosy friends, who contribute to the growing chaos surrounding Calvin's disguise. The party environment adds layers of complexity and comedy as Calvin faces many a humiliating scenario while evading detection.
As the plot unfolds through wild escapades, misunderstandings, and heartfelt moments, including a birthday party for Calvin that emphasizes his yearning for belonging, it becomes clear that what started as a comedy of errors ultimately transforms into a story about friendship, acceptance, and the unexpected bonds of family.
As Calvin finds himself in a whirlwind of events filled with misunderstandings, including numerous altercations with the mob and an emotional confrontation with Darryl, he must navigate his way back to the surface. His determination to safeguard the people he has come to care about leads to a climactic showdown with Walken and his goons. The culmination of Calvin's adventure sees him reclaim the diamond, revealing crucial truths and ultimately mending relationships that seemed fractured.
With a final nod toward a sense of family above all, the film wraps with a light-hearted touch celebrating the unconventional bonds formed throughout the journey, leaving audiences chuckling at the absurdity and charm of Calvin's escapades.
