The sky's the limit when estranged brothers - Joe and Brian Hackett reunite to run a commuter airline together. On the small island of Nantucket, the Hacketts run with a first-class crew of neighbors and co-workers, including lunch counter manager and childhood friend Helen Chappel. Their rival Roy Biggins keeps them on their guard, while sharp-tongued ex-stewardess Fay keeps them on their toes. Big-hearted Italian cab driver Antonio and eccentric mechanic Lowell always keep life around the terminal interesting.
