Stewie, the maniacal baby genius, is distracted from his plans for world domination after a near-death experience. Stewie plays nice thus creating an alternate goody-two-shoes version of himself. Convinced that a man on TV (his future self) must be his real father (after all, how could he possibly share genetic material with the dimwitted Peter?), Stewie sets off on a cross-country road trip to find him. But his incredible journey leads him to discoveries far more vile and shocking than anything found in his diaper.
