While stealing grain from a farmer, the group overhears the farmer worrying to his wife about how a man they framed for murder will be executed in six hours and they'll be in the clear. For reasons known only to himself, Steve and the others (with only Fitzhugh initially deferring) decide to clear the prisoner, Martin Reed.
They steal some knockout drugs from a pharmacy and contact a reporter with their story. The reporter agrees to smuggle Dan and Steve into the prison inside his camera. They then sneak into Reed's cell and use the knockout drugs on a guard so he can escape.
They tell Reed who was responsible and after the time for the execution passes, he confronts the farmers pretending to be a ghost. The Earthlings have rigged the phone so that the warden and the reporter can hear everything, as the farmers confess everything to the "ghost". They finally see through the ruse, but the police arrive to take them away.
