LaVon LaVern is a sexy woman who knows very little about stocks. Danny Partridge knows little about sex but a lot about stocks. Through Danny's stock tips, LaVon manages profit substantially on the market. The problem is LaVon's mobster boyfriend, Harry, thinks Danny (whose age he doesn't know) is trying to move-in on LaVon. Harry, whose hesitation to wed LaVon has caused her to lose interest in him, still blames Danny for what's happened. He hires two thugs, Rocco and Skee, to lean on the ten year old tot and the two men reluctantly do as they're told. They give Danny a verbal warning to stay away,or else. Danny, a realist at heart, scares himself sick thinking of the or else possibilities. He stakes out in his own home where his singing siblings can't get Danny to tell them what's wrong. Reuben thinks it's merely Danny's latent insanity coming to the fore. Shirley is absolutely convinced something's wrong when Danny loses interest in the economic situation. Ultimately, Harry learns of Danny's age and sends Rocco and Skee to find Danny, who runs at the sight of the approaching thugs. A frenzied chase through alley-ways ends with Rocco and Skee capturing him and bring him home to an embarrassed Harry and a relieved mom. LaVon finally gets Harry to I do. Rocco and Skee become firm friends with the little-boy broker who almost broke away.
