Police school rookie Lucy (Lucille Ball) gets herself assigned to handsome detective Bill Baker (Jack Kelly), who is participating in a stakeout to capture Green Scarf Louie (John Harmon), alias "The Lovers Lane Bandit." Making a shambles of the stakeout, Lucy must figure out a way to get back into Baker's good graces. Thus it is that she appoints herself a decoy to flush out the elusive Louie--while Viv (Vivian Vance) shows up in drag as Lucy's "boyfriend". ~ Hal Erickson, All Movie Guide
