BACKTRACK

When our hero is mysteriously given a device allowing the bearer to travel back in time, he inherits the dubious task of preventing the United States from suffering a terrorist attack of cataclysmic proportions. With this device, and a few other tricks up his armor-protecting sleeve, he must backtrack through a myriad of dangerous situations to discover the cause of the disaster. But finding the cause is only half the problem…he must prevent it.
