Frank Griffin's Gang is a notorious gang of outlaws and gunslingers. There is approximately 30 members of the gang. They are all cruel, blood thirsty and ready to kill whomever gets in their way. The gang has no scruples and will indiscriminately kill men, women and children. They're wanted in several states and were a target of the U.S army for a short time.
Frank Griffin and his gang hit the Tom Boy Mine in the town of Creede, to rob a train that was carrying payroll of up to $50,000. The gang blew the rails, causing the train to topple and crash. Aboard the train was J.B. Sloan, President of the Quicksilver Mining Company, holding the claim on the mine. Sloan's security were shot dead by members of the gang after they refused to put down their guns. Sloan himself was shot in the head next by Frank Griffin. Frank's gang then started rounding up and killing the passengers on board before looting the cash boxes. The payroll was then stolen by Roy Goode, Frank's adopted son and protege, who turned against the gang. Whilst the gang set off chasing after Roy for the money, miners from the Tom Boy arrived and apprehended Daryl and Donnie Devlin. They were left on the train after they were knocked unconscious by Roy who stopped them from raping a poor woman.
Marshal John Cook rode up to Creede with a posse of lawmen to take the Devlin twins into custody, however the town decided to lynch them instead before he could arrive. Frank Griffin's gang decided to turn back, and saved the twins before they were hung, killing everyone in Creede as they went and burning the town to the ground.
