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 (Eric McCormack), the team's leader; Marcy (Mackenzie Porter), a young, intellectually disabled woman in the care of her social worker, David (Patrick Gilmore); Trevor (Jared Paul Abrahamson), a high school quarterback; Carly (Nesta Marlee Cooper), a single mom in an abusive relationship; and Philip (Reilly Dolman), 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.
In Season 2, FBI Special Agent Grant MacLaren (Eric McCormack) and his team of time-travelling specialists attempt to navigate their 21st century lives while tasked with the mission of saving the future from a dystopian existence. The Travelers will face their most difficult obstacles yet, including the Faction, a deadly virus, and a mysterious new Traveler (Enrico Colantoni), all while continuing to live the everyday lives of the present-day host bodies over which they've taken.
The third season of Travelers finds Grant MacLaren and his team of highly-trained operatives from the future pushed to the limit and dealing with themes of loyalty, trust, death, and the ever-growing power of Artificial Intelligence. With their existence now leaked to the world, the team must find a way to keep knowledge of the Travelers program from the general public, while continuing to perform missions under the watchful eye of the FBI. Each team member will face their own personal breaking point, all while trying to stop the Faction, hunt down elusive Traveler 001, and to save the world from a terrible future.
