Ellie Mae lives on Primrose Hill with her good-hearted and fancy free mother, her drunken father, her younger sister and a mean-spirited grandmother. The Hill is not a good part of town, however. When she meets and falls for a hard-working man, they marry and she hides her past from him. When he discovers the truth it jeopardizes their marriage.

Alcoholic playboy Wallace MacDonald (as Bruce Armstrong) would like to sober up and become more responsible, after a drinking accident causes him to cripple little brother Pat Moore (as Jimmy Armstrong). Still, the lure of liquor makes him to sneak drinks at home, and go out partying with carefree showgirl Clara Bow (as Marilyn Merrill). He's promised Ms. Bow he'll quit drinking and gambling. Further complicating Mr. MacDonald's life are the bad checks he's been accumulating. Nasty Stuart Holmes (as Tom Canfield) and Tom Santschi (as "Big Joe" Snead) force MacDonald to join their diamond smuggling racket, in lieu of payment.
