Being a parent is tough; being a single parent is even tougher. So when injuries and his wife's death force ex-baseball player Tony Micelli (Tony Danza) into retirement, and a single mom, high powered advertising executive Angela Bower (Judith Light), needed someone to run her household, it was a match made in heaven. Or was it? After convincing her free spirited, mischievous mother, Mona Robinson (Katherine Helmond), that hiring Tony is the right thing to do, the less-than-tidy Angela welcomes him and his daughter Samantha (Alyssa Milano) as the live-in housekeeper for her and her son Jonathan (Danny Pintauro). And while their relationship starts out businesslike and platonic, becoming best friends and confidants makes it hard for two attractive, single adults living under one roof to resist their more grown-up impulses.
