The Griffin family find themselves on the wackiest of adventures when Ernie The Giant Chicken steals Stewie's time-machine and travels back in time to recruit the worst people in history to re-shape Quahog (and the planet) in their image. Peter tries to help Stewie build his own time machine, but the clock is ticking, as Ernie wants to use the Griffins as his own personal slaves while a certain German dictator lays out the plans for World War 3.
