In this episode, Peter Griffin, Brian Griffin, and Stewie Griffin accidentally travel to a parallel universe after Peter uses a remote control to change the channel on a TV set with infinite universes. In this particular universe, Stewie has become a ruthless dictator and Brian is a Black Ops agent working for the CIA.
It's worth noting that while the episode features a Black Ops storyline, it's played for comedic effect and doesn't delve deep into the complexities of the genre. It's a classic Family Guy episode with its usual blend of absurdity and humor.
