Thrill Seekers (also known as The Time Shifters) is a 1999 science fiction television film directed by Mario Azzopardi and starring Casper Van Dien, Catherine Bell, Julian Richings and Martin Sheen.

[1][2] Tom Merrick (Van Dien) is a TV reporter filming a live segment on a fire at a power plant.

The averted disaster causes changes in the future, so Grifasi (Sheen), the head of Thrill Seekers, sends agents Cortez and Felder to the past to stop Merrick.

Merrick manages to disconnect the locomotive from the rest of the train, but the time traveler remains behind and is killed.

Cortez and Felder are informed by Grifasi that the prevention of the train wreck has had a huge impact on the future.

While checking the time-traveling device, Merrick learns of another catastrophe: a fire at Copps Coliseum that will kill over 11,000 people, including his ex-wife and son.

The only way to reset the timeline is to make sure the Copps Coliseum fire occurs in order to prevent the timeline from altering too much to be recoverable and then to travel to the past to prevent Merrick from saving the lives of the people who will go on to cause the California disaster in the future.

The agents pursue Merrick and blow up his car with Elisabeth in it, then travel to the stadium and plant multiple explosive devices.
