But Spud Warner (Eddie Acuff), a newspaper photographer, there with newspaper reporter Rusty Farrell (Douglas Fowley), takes a snowball from her basket and Nick receives an empty one. The Blue Diamond disappears. Aided by a private investigator, Ellen Dale (Pamela Blake), Chick finds himself pitted against the criminals searching for the missing Blue Diamond...
