Few folks remember that the U.S. Mint in Denver was robbed of $200,000 in 1922. One robber was found dead. The others vanished with the money. Even fewer people know that at the same time, the Lawn Lake Dam was being built in Rocky Mountain National Park.
Assisted by glamourous detective Vi Coteau, Ranger Tim McIntyre investigates the murders of two workers at Lawn Lake and finds two women acting suspiciously. Also suspicious is the fact that the mint was robbed by two teams of raiders, each team with two men and two women... who needed to hide the loot and themselves. That meant eight people to share the two hundred grand-unless some of them end up dead.
