Head of the Phoenix Agency's fledgling Psi division, Mia Romeo wants recognition for her team's psychic abilities to combat crime. After a frightening vision, she doesn't question her telepathic instincts to board a train in San Antonio alone, not knowing where she's going until she reaches El Paso. Her gift spirals her into a sinister premonition centered on two men boarding her train, assassins from a cartel Phoenix has in its crosshairs. She uses her newfound telepathic gift to warn their target and head off the carnage, but the man they're after has a powerful mind barrier she can't penetrate.
