Police officer Max Walker has been offered a position with the TEC but is unsure whether or not to accept. While at home with his wife Melissa, he is attacked by unknown assailants and witnesses the house explode, killing her. Ten years later, Walker is a veteran of the TEC working under Commissioner Eugene Matuzak, who sends him back to 1929 to prevent his former partner, Lyle Atwood, from using knowledge of the future to financially benefit from the U.S. stock market crash.

Fearing that McComb will erase him from history, Atwood attempts to jump to his death, but Walker catches him mid-leap and returns to 2004. Refusing to testify, Atwood is sentenced to execution and is returned to 1929 where he resumes falling to his death.
