Frontier

When portals showed up around the world and gave access to a more technologically advanced Earth, the government created a group known as "Pathfinders​" to explore the resources of the Other Side. Exploitation, however, led the Other Side to counterattack, resulting in the so-called Great War that wiped out almost all the Earth's resources. The portals were controlled to prevent the passage to the Other Side and the Pathfinders were disconnected.
Max Powell is a former Pathfinder who makes a living hunting for remains of machines from the Other Side to sell. Victim of an accident that deformed her body and killed her platoon, including her girlfriend Lisa, she receives a message from Lt. Reynolds saying that Lisa is not only alive on the Other Side, as she may also be victim of a grand plan that aims to exterminate the Earth once for all. Lt. Reynolds believes that Max is the only one able to stop this catastrophe, but is she able to face all the ghosts of the past and save Lisa?
