Marcy puts herself in a near-death state to recover her lost memories from when she was reset. The memories she receives include those of the original host Marcy, showing that the host's intellectual disability was caused by Vincent/001 testing Simon's incomplete consciousness transfer technology on her. While she is out of commission, Mac and the rest of the team are ordered to provide Hall with backup in protecting the future 53rd President of the United States, who is currently a prepubescent girl.
Hundreds of years from now, the last surviving humans discover the means of sending consciousness back through time, directly into people in the 21st century. These Travelers assume the lives of seemingly random people, while secretly working as teams to perform missions in order to save humanity from a terrible future. These travelers are: FBI Special Agent Grant MacLaren, the team's leader; Marcy, a young, intellectually disabled woman in the care of her social worker, David; Trevor, a high school quarterback; Carly, a single mom in an abusive relationship; and Philip, a heroin-addicted college student. Armed only with their knowledge of history and an archive of social media profiles, the travelers discover that 21st century lives and relationships are as much a challenge as their high-stakes missions.
