Ruth Holt is the efficient private secretary to young architect Elwood Adams. Her polar opposite is Adams' indolent, spendthrift wife Francine, faults which Adams, blinded by his love for her, doesn’t see. Looking to cause trouble, a lounge lizard acquaintance of Francine’s spreads gossip to make her jealous of Ruth. In a business crisis Adams introduces Ruth as his wife to banker Amos Martin but when Francine finds out she flies into a rage and denounces Ruth. After a series of complicated events Ruth reunites the Adams couple and marries the banker.

The second and last of Eddie Cantor's silent vehicles, Special Delivery casts the wide-eyed comedian as a hapless mailman. While going through his swiftly appointed rounds, Eddie stumbles upon a gang of crooks who are planning a large-scale confidence scam. He exposes the villains and wins the love of heroine Madge (Jobyna Ralston). Though Cantor was a fine physical comic, he didn't truly score in films until the arrival of talkies allowed his fans to hear as well as see him. Special Delivery was directed by "William Goodrich," who in reality was comedian Fatty Arbuckle, hoping to stage a comeback after the sex scandal that destroyed his career.
