In the lab, Carlin meets a team of scientists who have been studying a new technology developed by the government to look back in time within a specific radius. This technology allows them to see, hear, and even smell what happened in the past. Carlin soon discovers that they are using this technology to investigate the bombing of the ferry.
As Carlin studies the past, he begins to realize that he can use the time-shifting device to go back in time and save the lives of those who died in the explosion, including the woman he had just met on the ferry. Using the technology to revisit the past, Carlin races against time in an attempt to prevent the explosion and catch the terrorist responsible.
Throughout his journey, Carlin learns that the technology has limitations, and interfering with past events can have unforeseen and dangerous consequences. As he works to prevent the disaster, Carlin must also grapple with ethical questions about the use of this new technology.
