Anne and Don, married ten years, are on vacation in Florida. As the play begins, Anne is inanely chattering on about beaches, seagulls and garbage dumps. Don, fed up with Anne's incessant chatter, walks away leaving Anne, much to her surprise, sitting on the beach alone. Don has gone to visit his friend Jim, a man of little insight but great obsession about golf, to tell him that he has left Anne. Jim, in turn, has just returned from a golfing vacation to discover his wife, Sandy, has apparently left him. George, a seagull who lives a contented life with his wife, Ethel, on the Staten Island landfill, has just arrived on the Florida beach and meets Fred, a seagull without ties but with a dark past. The Secret Life Of Seagulls follows these four humans and Fred as they attempt to define themselves, their lives, relationships and values. George, the Staten Island seagull, however, is quite content being who he is.
