Former federal agent Lena, in pursuit of the truth behind her husband's murder, infiltrates the ranks of tech giant Elias as a private security guard under an assumed name. Initially convinced that this cold and dangerous man is linked to the shadowy organization "Raven", Lena discovers through repeated tests and life-and-death confrontations that Elias is also hunting the real perpetrator. As long-buried evidence surfaces, the two shift from hunter and prey to allies fighting side by side, while the true enemy unexpectedly lurks among those Lena trusts most.
