What if the most dangerous criminal in the city was also the smallest? In this outrageous comedy from director Keenen Ivory Wayans, diminutive thief Calvin Sims, played by Marlon Wayans, is a master of disguise who pulls off heists by posing as a baby. After a jewel theft goes awry, he plants the stolen diamond on unsuspecting suburbanite Vanessa, portrayed by Kerry Washington. To retrieve it, Calvin hatches his most audacious plan yet: he gets himself "adopted" by Vanessa and her husband Darryl, played by Shawn Wayans, who are desperate to start a family. As Calvin, the world's most manipulative and foul-mouthed "infant," wreaks havoc in their home, Darryl begins to suspect their new bundle of joy is anything but innocent. This high-concept farce blends physical comedy with a fish-out-of-water story, as the couple navigates the chaotic trials of first-time parenthood with a "baby" whose criminal instincts threaten to tear their world apart.
