One day in the wild, wild west, a famous scientist is found dead. Or better: Decapitated by a devilish device, as it seems. Special Agent Artemus Gordon, quite inventive himself, finds out about the man’s last sight and is forced to team up with James West, a man who relys on nothing but his gun. They first suspect General ``Bloodbath`` McGrath to be responsible for the killing, but as he’s not bright enough to invent the flying decapitation device himself, a more evil mastermind behind the scenery is soon proven to exist. Dr. Arliss Loveless, who, by the way, has kidnapped the nation’s best scientists, seems to plan on taking a major part of the country as his personal property. But Dr. Loveless did not spend enough thoughts about possible intervention from two men, who may get a little distracted by the sudden appearance of beautiful Rita Escobar, daughter to one of the abducted scientists.
