A string of bank robberies along the East Coast has solidified his place in infamy but may send him to an early grave. Olivia "Liv" O'Reilly is a woman haunted by her past and her disastrous engagement to the heir of a powerful Boston mob family.
Forced to live life on the run because of the relentless pursuit of her former fiancé, she dreams of returning home to her family in Boston. But fate has a different plan when her ex-boyfriend Declan Quinn walks into the bank in northern Pennsylvania where Olivia works, changing both of their lives in an instant. Driven by desperation, Declan takes Olivia hostage, hoping to keep her from talking to the authorities about his latest heist.
