Stewie creates the universe (or so he says) in order to get back into it. It seems that he and Brian get themselves trapped outside the time-space continuum after fighting near his time machine's control panel, and a big bang is the only way back. Then his diabolical half brother, Bertram (voice of Wallace Shawn), gets his hands on the machine. This is bad news for both Stewie and the rest of the universe.
