Death grants Peter's wish of going back in time to be 18 again for one night so that he can sow his wild oats. But when he discovers he has altered the present so that he's married to Molly Ringwald and Lois to Quagmire, he and Brian (who happened to tag along with him to the past) must try and return the timeline to normal.
