Julian Lethercore is on the run, dodging police across the state of Colorado to reach Senator Pershing at his estate in the Rockies. Meanwhile, a menacing and unexpected midnight visitor at Kate Cliffbridge's home sends her comfortable suburban life spinning into disarray, dredging up secrets from her past as an experimental subject in a top-secret program. Her rescuer, the brilliant former scientist Stephen Hack, brings his own set of problems: he's a wanted man, the sole survivor of a covert government facility. The two of them turn to an unlikely ally to smuggle them out of the U.S.: white supremacists.
