Private investigator Bradford Galt has moved from San Francisco to New York to escape a troubled past. He blames his former partner Tony Jardine for his problems. Complicating matters, he is being hounded by New York Police Lieutenant Frank Reeves and finds that he is being followed by a thug in a white suit. After a little rough "persuasion", the thug admits he has been hired by Jardine.
Galt suspects Jardine is trying to frame him for a murder. But it turns out that Jardine is just part of a wider-ranging conspiracy involving a wealthy art gallery owner, Hardy Cathcart. With the help of his sharp-witted secretary Kathleen (Lucille Ball), Galt is able to overcome all these obstacles and clear himself.
