"Extraction" is based on a comic titled "Ciudad" by author Ande Parks, and as it turns out, the comic's ending is less ambiguous the film's conclusion. That said, "Extraction" alters "Ciudad" in certain key ways, the most notable of which is the fact that, whereas in "Extraction" Tyler Rake is escorting a boy named Ovi (Rudhraksh Jaiswal), in the original story Tyler is responsible for a girl named Eva.
Nevertheless, the climactic "Extraction" scene in which Tyler's pursuers shoot him and he falls into a river is adapted from the "Ciudad" comic. But, while that moment may be the last viewers see of Tyler in the film, the comic continues, and reveals that Tyler arrives intact at a hospital in Argentina.
Viewers, then, can simply presume that in the "Extraction" film series, just as in "Ciudad" before it, Tyler survives both his bullet wounds and the possibility of drowning long enough to ensure his rescue.
