Architect Peter Mitchell (Tom Selleck) has an ex in Rebecca (Margaret Colin). Michael Kellam (Steve Guttenberg) is a sensitive cartoonist. Jack Holden (Ted Danson) is a playboy actor. The three bachelors happily share a Manhattan penthouse with a long line of women coming in and out. Then somebody leaves a baby at their doorstep. A note indicates that Mary is the result of an union between Jack and Sylvia (Nancy Travis). Jack is away doing a TV movie. Peter and Michael are forced to deal with the baby. Jack has a package of drugs delivered to the apartment which is to be picked up by two men. Peter and Michael mistakenly assume the baby to be the package. Narcotics officer Sgt. Melkowitz (Philip Bosco) come to question the guys.

The combination of the three stars makes this work. Selleck is terrific. This has good comedy and some awkward stuff. I can do without the heroin. It takes the movie down a dark alley. The tone is completely wrong. I would have liked more with Rebecca and Sylvia doesn't need to be British. Overall, it's a mix bag with some laughs.
