THRUSH wants to gain control of a mineral known as Tri-Tanium D, which when processed can be used in a lethal death ray. The only known location of this mineral is the ghost town of Furnace Flats in Death Valley. Furnace Flats is owned by Mesquite Swede a grizzled old prospector who dies from a heart attack shortly after an attack by THRUSH. His will stipulates that the town will go to whichever lady can duplicate a famous ride through Devil's Domain made by Death Valley Flossie. A race is setup between April, Dolly X (a THRUSH agent) and Ladybug Byrd. The identity of Mesquite Swede's daughter could also be a factor in determining ownership.
