Scat Sweeney, and Hot Lips Barton, two out of work musicians, stow away on board a Rio bound ship, after accidentally setting fire to the big top of a circus. They then get mixed up with a potential suicide Lucia, who first thanks them, then unexpectedly turns them over to the ship's captain. When they find out that she has been hypnotized, to go through a marriage of convenience, when the ship reaches Rio, the boys turn up at the ceremony, in order to stop the wedding, and to help catch the crooks.
Unfortunately the movie Road to Rio is not yet available on HBO Max.
