Check and Double Check

　　Amos and Andy run the "Fresh Air Taxicab Company, Incorporated", so named because their one taxi has no top. Their old vehicle has broken down, causing a traffic jam. Stuck in the traffic jam are John Blair and his wife, who were on their way to meet an old family friend at the train station, Richard Williams. When the Blairs do not show up, he makes his own way to their house, where he meets their daughter, Jean, who was also his childhood sweetheart. The two reignite their old flame, much to the chagrin of Ralph Crawford, who has been attempting to woo Jean himself.
　　That night, prior to attending a meeting at their lodge, the Mystic Knights of the Sea, they are hired to transport Duke Ellington and His Cotton Club band to a party being given at the Blair estate. While they are on their way, Richard is confiding to John Blair his feelings for his daughter, and also stating that he has no intention of pursuing Jean unless he can afford to start his own business to support them. After the death of his father, Richard's family lost all their money. He has come up to New York because his grandfather used to own a large home in Harlem, and he hopes to be able to find the deed to it, in order to sell it for the money needed to start his business. He thinks the deed must be hidden somewhere on the property itself. Unknown to Blair or Richard, is that Ralph is eavesdropping on their conversation.
　　After his discussion with Blair, Richard runs into Amos and Andy, who used to work for his father down south, and they are all happy to see one another. Having delivered their fare, the two cab drivers rush back to town to attend their lodge meeting. The lodge has an annual tradition where a pair of members must spend a night in a haunted house in Harlem, and find a document labeled, "Check and Double Check". Once they find it, they are to replace it, in a different location, with their own version, for the lodge members to find the following year. The haunted house in question in none other than the house previously owned by Richard's grandfather.
　　As Amos and Andy are searching for their document, Ralph is also in the house with several of his cohorts, searching for the deed, in order to thwart Richard's chances with Jean. Amos and Andy find their document, but then realize they did not bring any other paper to write their message on and secrete for their lodge brothers. In searching for something to write on, they stumble on the deed to premises. As they are about to write their message on the back, they are interrupted by Ralph and his friends, who believe that the two have found the deed. In the confusion which ensues, the cab drivers hand over what everyone believes is the deed, before they scamper out of the building. However, when they return to the lodge, they realize that they had given the Check and Double Check paper to Ralph, instead of the dead. They do not know the importance of the document they have, but they recognized Richard's grandfather's signature on it, and intend to deliver it to Richard the following day.
　　After failing to find the deed, a heartbroken Richard leaves for the railway station, intending to return home. Amos and Andy arrive at the Blair house too late to give him the deed, but race to the station and are able to hand over the deed just before Richard's train leaves. Now with the deed, Richard can sell the house, open his business, and marry Jean.
