Paramutual Pictures wants to know where all the money is going so they hire Morty to be their spy. Morty works for Mr. Sneak and gets a job in the mail room so that he can have access to the lot. But all that Morty ever finds is that he can cause havoc no matter what he does.

Determined to cut wasteful expenditures, T. P., the head of Paramutual Pictures, selects dimwitted paperhanger Morty Tashman to spy on studio employees while posing as an errand boy. Almost immediately havoc reigns as the well-meaning but disaster-prone Morty blunders through a series of calamities. He disrupts the filming of a western, accidentally becomes the escort of a voluptuous European beauty attending a Hollywood premiere, panics the studio stenographic department, and ruins a sound-recording session. Finally, he turns a birthday party for a "great star" into a total shambles by almost drowning the woman in a flood of exploding champagne. The distraught T. P. decides to fire Morty before the entire studio is destroyed. Two top directors, however, who witnessed Morty's antics at the birthday party, regard him as a potential star comedian, and T. P. is persuaded to sign him as the new reigning comic of Paramutual Pictures.
