A typical day at a Chicago travel agency turns deadly when Blayne Keller witnesses to a mafia murder. Overnight, her life is turned upside down and she is thrust into WITSEC, the Federal Witness Protection Program, against her wishes. But the mob is determined to keep her from testifying and has someone on the inside leaking information about her every move. Only Alexi Nikolos, an alluring but dangerous WITSEC Inspector with an agenda of her own, can keep Blayne alive - but it's not an easy task when the sparks between them are flying faster than the bullets aimed at their heads.
