Synopsis for
3 Men and a Little Lady (1990) More at IMDbPro »

Peter (Tom Selleck), Michael (Steve Guttenberg) and Jack (Ted Danson) are now dedicated "fathers" to five year old Mary (Robin Weisman). Everything is going along fine until Mary's mother, Sylvia (Nancy Travis), begins thinking she needs more stability in her life and doesn't think any of her roomates are up to the task.

Sylvia doesn't know that Peter has fallen in love with her but is hesitant to act since he feels his best friend, and Mary's biological father, Jack should step up and marry her so she accepts a marriage proposal from the director of her play, Edward (Christopher Cazenove). The wedding is to be in England and shortly we learn that Edward plans to move Sylvia and Mary there as well. Faced with the prospect of losing Mary from their lives Michael and Jack convince Peter to finally ask Sylvia to marry him instead of the unlikable, but willing, Edward and the three go to great lengths to break them up.

In the end Sylvia realizes that Edward is a scoundrel and that she really likes Peter as well so we get the typical and expected happy ending with Sylvia leaving Edward at the alter to return to New York.
