While on their honeymoon, a reporter and his new bride stumble upon a ring of fifth columnists.

Set in a western town, the stooges are working as waiters in a saloon with the three girls they hope to marry. The proprietor of the saloon is a crook who, with his partner, has buried $40,000 of stolen money. The boys go prospecting in hopes of raising enough money to pay off the debts of their fiancée father, who owes money to their boss. They dig up the stolen money, which the crooks recognize as their loot and abscond with. A wild chase ensues, ending with the bad guy's car crashing into the Sheriff's office.

The Stooges are key witnesses at a murder trial. Their friend Gail Tempest, who dances at the Black Bottom cafe where the Stooges are musicians, is accused of killing Kirk Robin.

Dr. Paul Carruthers is frustrated because he thinks his employers, Mary Heath and Henry Morton, have cheated him out of the company's profits. He decides to get revenge by altering bats to grow twice their normal size and training them to attack when they smell a perfume of his own making. He mixes the perfume into a lotion, which he offers as a gift to Mary and Henry. When they turn up dead, a newspaper reporter decides to investigate.
