Three men are found murdered on consecutive nights with the killer following the same modus operandi - the victims were all shot between the eyes and the third button on their vest was removed. The Denver detectives must determine what connection the men had with each other and Smith discovers information that links the crimes to the beautiful proprietress of a popular local casino.
