One son ... two fathers? Robin Williams and Billy Crystal star as prospective dads in search of the same runaway boy that each thinks may be his child. From director Ivan Reitman (Ghostbusters movies) comes the madcap comedy adventure Fathers' Day. Dale Putley (Williams--The Birdcage, Mrs. Doubtfire) and Jack Lawrence (Crystal--City Slickers films, When Harry Met Sally...) never met, yet they both share something in common: ex-girlfriend Colette (Nastassja Kinski). To enlist their aid in tracking down her missing son, Colette tells each of her dumbfounded ex-lovers that he fathered the child to which she gave birth 16 years ago. Inadvertently trapped on the road together, these two strangers grow even stranger as they engage in the hilarious hijinks that can only happen when it's Fathers' Day.
