A young executive is trying to convince an airline to sponsor a travel show on television, but he's not getting anywhere. When he tells his fiancé that he may have to postpone their honeymoon, she goes off on him, and as he backs away from her he hits his head on a fire extinguisher and knocks himself out. While unconscious he dreams his own version of the show he's trying so hard to sell.
