Filmed version of the hit Broadway show with two of the original stars. Set in the backyard of a blue collar South Philadelphia neighborhood early in the summer of 1973, the comedy-drama focuses on the 21st birthday celebration of Harvard student Francis Geminiani. In attendance are his divorced blue collar father Fran and Frans widowed girlfriend Lucille, next-door neighbor Bunny Weinberger and her overweight son Herschel, and Francis classmates, the wealthy WASP Hastings siblings; Judith (who seeks romance with Francis) and Randy (the object of Francis unexpressed affection), who have arrived unexpectedly, much to their friends dismay. All are dysfunctional to varying degrees, and the interactions among them provide the play with its comic and dramatic moments.
