Recounting to his children how he met their mother, Ted (Josh Radnor) describes the heady days of his urban bachelorhood, when he was surrounded by his pals Marshall (Jason Segel), Lily (Alyson Hannigan) and Barney (a scene-stealing Neil Patrick Harris). Through a series of mishaps as unpredictable as life itself, Ted gets closer to finding "the one" in this fourth season of the Emmy nominee for Best Comedy series, set 25 years in the future.
