Roger, Dwayne and Rerun, the fun-loving teens from the popular mid-1970s comedy "What's Happening," are back for more laughs in this sequel series that picks up seven years later. Now adults, newlywed Roger is a struggling writer, while his two buddies, still bachelors, are sharing an apartment. Dwayne is now a computer programmer, and Rerun, always the clown of the group, has found his niche as a used car salesman.
