In the year 2030, Ted Mosby (voiced by Bob Saget) gathers his daughter and son to tell them the story of how he met their mother.
After Stella and Ted make the spontaneous decision to get married in three days, the presence of their exes destroys what was to be the "happiest day of their lives." Robin quits her job, returns from Japan, and suggests she may have feelings for Ted, and Stella reunites with her ex-boyfriend and father of her daughter and leaves Ted at the altar. Barney ruins a chance to reunite with Robin.
