A highly organized outlaw gang has robbed banks, trains and stagecoaches throughout southern Arizona. When Marshal Fry learns that four of the West's most notorious outlaws - Billy the Kid, Curly Bill Brocius, Ike Clanton and Johnny Ringo - have dropped out of sight, he fears that they have joined forces. Clay McCord stumbles upon a clue to the gang's whereabouts and, using a pair of homing pigeons, hopes to communicate their location to Simon Fry before their next raid. (thetvdb.com)
