Jim Henson's beloved characters Kermit, Oscar, Bert, Ernie and Cookie Monster - plus other Sesame Street regulars - join Big Bird in a bighearted, cross-country adventure. A meddling social worker sends poor Big Bird off to live with a feathered foster family in Illinois. But try as he might, he doesn't fit in and runs away to return to Sesame Street. Can his old friends find him before he runs "afowl" of trouble en route? Be on the lookout - and be there for big entertainment from guest stars Chevy Chase, Jogn Candy, Sandra Bernhard, Waylon Jennings and more.
