The trio own a furniture shop ("Ye Olde Furniture Shoppe: Antiques Made While U Waite") who are staining some furniture they have delivered to Miss Scudder (Jean Willes), an attractive curly-haired brunette who owns a boarding house. While attending to their duties (and nearly destroying the furniture in the process), several new boarders at Miss Scudder's place are actually a trio of crooks who have just robbed a jewelry store. The Stooges are held at gunpoint while Miss Scudder is tied up and gagged in her kitchen while the crooks ransack the house to steal several valuable heirlooms in her possession. The Stooges and Miss Scudder work together and unravel the crook's plot.
A Snitch in Time is a particularly violent film for the Stooges. The topper remains 1943's They Stooge to Conga, but A Snitch in Time runs a close second. Interestingly, this film was directed by Edward Bernds, who always maintained that the Stooges did not have to be violent for the sake of being violent. Columbia short subject head and director Jules White, on the other hand, was notorious for the excessive abuse in his shorts.
