Only the Lonely

“Before he can tie the knot, he has to untie the apron strings.”

Why does a Chicago policeman in his forties still live under his mother's roof? Danny Muldoon (John Candy) never moved out, and Rose (Maureen O'Hara) sees no reason he should. Then he meets Theresa Luna (Ally Sheedy), a shy girl from the funeral parlour, and Chris Columbus follows the three of them as Rose decides she doesn't like her.
