The mission of The Watchdog of Time is to make sure that people on each planet it is overseeing maintain linear time in their lives. When disruptions occur in an individual's time stream, the Watchdog makes the repair so that the person has no memory of what has transpired and is returned to their normal life. In the year 2049 the system has gone awry, threatening the survival of the Earth. It is now up to a select group of victims to work with the Watchdog to stave off what could be a death spiral for the Earth.
