Lyle Swann, a champion off-road racer, enters a motorcycle rally in the California desert. Unbeknownst to him, an experimental time-travel project is being conducted nearby. During a high-speed race, Lyle inadvertently crosses paths with the experiment's temporal field and is transported back to the year 1875. Confused and disoriented, he finds himself in the rugged old west, armed only with his modern motorcycle and gear.

He befriends a compassionate woman named Claire, who helps him navigate this perilous new environment. Lyle's primary goal becomes finding a way back to his time, but complications arise as various factions, including a cunning outlaw, seek to exploit his advanced technology for their own gain. Lyle's journey becomes a desperate race against time as he confronts the dangers of the old west and the dramatic consequences of his inadvertent journey through time.
