Ted Higgins and his pal Homer, two window washers in New York City, are mistaken for messengers by a tough gambler named Mike Craig and instructed to pick up fifty-thousand dollars in cash from a Mr. Stewart. After Stewart hands over the money, his thugs follow Ted and Homer, and Homer ducks into a mail room and mails the money to Craig. When they report to Craig, he believes that they stole his money and holds them hostage all night in his office. The next morning, Ted and Homer anxiously await the arrival of the money in the mail, but the envelope contains only a face powder sample. While Homer wasn't looking, the envelope was accidentally switched and became part of a massive promotional mailing for a cosmetics company. Craig then gives Ted and Homer forty-eight hours to come up with the money. While being tailed by Craig's thugs, Ted and Homer hunt down the recipient of their original envelope, and it turns out to be Carol Blair, a personal secretary. Carol explains apologetically that she has spent almost all of the money, and begs Craig to give Ted and Homer more time. Craig, who needs the money to pay back his bookie, J. C. McBride, calls McBride for an extension, and McBride, who by reputation never loses, gives him a 30:1 racing tip on a horse called "Lolly C." Carol, Ted and Homer go with the remaining cash to the racetrack and bet on Lolly C, but McBride changes his bet at the last minute and Lolly C loses. Meanwhile, they meet McBride at the track, but he introduces himself as Julius Caesar, and they do not realize who he is. McBride quickly befriends the trio, and that night, all four dine at an expensive restaurant, where Ted and Homer hope to get arrested for not paying the check in order to avoid Craig's vicious thugs. Craig arrives and hauls them away to a sand and gravel company before Carol realizes that Julius Caesar is McBride. Carol, meanwhile, has won $50,000 from McBride in penny bets at the bar, and they go to settle the debt. Craig is about to have Ted and Homer's feet stuck in cement and thrown into the river when Carol arrives with McBride and saves them. Ted and Homer demand payment from Craig for their original messenger service, then push him and his thugs into the wet cement for prints of their backsides. Carol then kisses Homer.
