When Archie gets Veronica a stamp for a letter, he grabs a rare stamp valued at a $1000. The stamp was part of Mr. Lodge's collection and was sitting on his desk.
Mr. Lodge's magnificent diamond is protected by state-of-the art booby traps, but they're no match for the C.R.U.S.H. agent Smoke Man, who can vaporize in and out of keyholes. It's up to A.R.C.H.I.E. and J.U.G.H.E.A.D. to stop this condensed C.R.U.S.H. creep.
Veronica guilt-trips her father into financing an appearance by the Little Archies at an out of town music festival. Then Archie boards the wrong train.
