The Flamethrower, that arson-loving C.R.U.S.H. agent, is back with his powers restored. This time his plan is to use flame-throwing fireflies to wipe out P.O.P. and Mr. Lodge's plant. But with the help of P.O.P.'s science lab, A.R.C.H.I.E. manages to re-direct the fireflies to destroy C.R.U.S.H. buildings, and finally their own master.; The Archies are called in by Mr. Lodge for assistance when an industrial spy steals his company's "Go-Go Gun," a gun that makes things go-go-gone. The merry madcap musicians pursue the bad guy as he zaps people and makes them go-go-go away.
