Even if you're not a Stargate fan, you should definitely give Travelers a chance. It's a show that really knows what it's doing. It knows how to tell stories that are morally deep, intellectually clever and emotionally satisfying, all at the same time. We've seen some really good SF on TV lately, but Travelers is the one show that I'm most excited to see more of. A LOT more, hopefully.
Mac investigates a mass arrival of Travelers, while also trying to repair his marriage with Kat. Philip is given assistance with his addiction from fellow Traveler 4514, Jenny. Marcy treats David for PTSD, but is dealing with feelings of detachment and disassociation herself. Carly and Jeff try and clean up their act for Child Protective Services and regain custody of their son. Trevor and Grace bond in the hospital while recovering from their injuries.
Carly loses custody of her son until the trial. Grace is due to die, so Trevor kidnaps her to save her life. Believing he is insane, she flees and is overwritten despite having avoided the accident that would have killed her. Grace and another newly arrived traveler, Ellis, are computer programmers who have fled an anti-Director faction in the future. Ellis has developed a code that is sought by this faction, and has returned to the 21st century to keep it from them. David and Marcy consummate their relationship. However, her condition worsens and Boyd stabilizes her, but Marcy is near death. In the future, Grace was in charge of social media research and identifying the candidates. She wants to correct Marcy's condition with an experimental overwrite. She offers to redirect Marcy's original transfer into the functional part of her brain, saving her at the cost of her 21st-century memories. MacLaren lets Marcy decide, and she decides to speak to David first. However, her condition becomes critical shortly before David returns home, and she is overwritten by her earlier self. Her team introduces her to David.
Today Hawaii is a bold showcase for farm-to-table fusion cuisine, culturally conscious fashion and innovation. Visitors will find themselves spoiled for options between romantic boutique getaways and family friendly five star resorts. High-end retailers have put Hawaii on the map of world-class shopping destinations, and Hawaii’s passionate chefs have created a foodie frenzy here. As far forward as Hawaii has evolved, those looking for a walk back in time can still find Old Hawaii tucked away off the beaten paths. And the ancient stories still exist in the lovely hula hands of dancers who have given themselves as keepers of the culture.
After asking Marcy to move out, David admits he cannot bear to be without her. She tells him she is dying, and they kiss. Trevor tries to connect with his father. Jeff files assault charges, preventing Carly from finding a job. She asks him to take the baby for an afternoon, unaware he has tipped Kat off to Carly's relationship with MacLaren. Under orders, a traveler murders her host's Cabinet-member husband, and instructs MacLaren to board a flight as Congressman Bishop's seatmate. In flight, MacLaren learns he is to activate a stasis field to save himself and Bishop, while all others aboard will die in a crash. MacLaren discovers Kat followed him on board, believing she would witness his infidelity. He instructs Kat and Bishop to use the stasis device, and attempts to survive impact unaided, using only Philip's knowledge of the crash. At the crash site, the team resuscitate Kat and Bishop, and Bishop is overwritten. To Carly's dismay, MacLaren is taken away by traveler paramedics before the team can reach him.
During an update for historians, one of them dies from cerebral overload and is taken over by another traveler. The faction then breaks in and kidnaps the historians. A Blackbox is a device used to extract information from an unconscious or dying person and the team uses one to access a critically injured Hall to ascertain the location of historians. Jeff reaches out to his police sergeant to get his job back and is told to get help from a social worker first. Philip is questioned by the faction. Philip is given time with Kyle as a gesture of good will, who states that he sympathizes with the faction's goal, especially since he just saw another historian die during the update. Faction saves a TELL that Kyle provided to gain his support. Jeff reaches out to David to sign his therapy form for him to get his job back. David agrees to help as a social worker with Jeff's addiction, which the traveler doesn't actually have. Hall is able to relay information from when he was tracking his team's historian showing he ran into a faction team and was shot climbing a fence. He reveals that it was Kyle and Luca from his own team that shot him. Hall is able to show the team the location of the historians and the team is dispatched. While with David, Jeff receives a message to meet up at the location for tactical support. Philip is able to escape before being cornered by Kyle and Luca. Maclaren's team shows up just in time to save Philip and kills Luca and Kyle. The team saves all the historians while taking out many of the faction. Hall is told he saved them all and is able to pass away in peace knowing that. Jeff and Carly reconnect. Philip is seen throwing out his yellow pills that historians have to take.
To prevent an explosion that kills thousands, the team steals antimatter from a military convoy. The material's intended recipient is a new traveler who fails to prevent his host's suicide, forcing the team to improvise. After failing to upgrade their containment device, the team returns the antimatter to its origin facility. They form a tenuous alliance with Dr. Delaney, who produced the antimatter; history records her as complicit in the weaponization of antimatter, but she actually opposes Major Gleason's ambitions. MacLaren informs Delaney that they will return soon. Philip retains his host's heroin addiction. MacLaren meets his wife, Kat, but also resumes a preexisting relationship with Carly. Marcy works to build trust with a confused David.
