 In Texas of 1899, one-time outlaw, now sheriff John Grail confronts his former partners-in-crime who robbed a bank in his town. Trapped by a posse on Comanche burial grounds, the lawman and his old gang are ready to shoot each other to death when a lightning bolt strikes. Instead of killing them, it transports them to Houston in the year 1986. Using the ill-gotten gains of the bank robbery, now worth fifty times its original value, the time-tossed gunmen struggle to adapt in this new century. However, inner turmoil threaten to tear them apart until they band together to fight a common foe, a criminal of the modern age.
