Security expert and bodyguard Tanner Keane is hired by millionaire inventor Christopher Hilliard to rescue his wife Madison from kidnappers. When the rescue takes a tragic turn, and one of his men is killed in the crossfire, Madison begs him to not release her to her husband, telling him that he was the one behind the kidnapping, and fears he will kill her.
Tanner is not sure what to believe, but takes her to a safe house. When he advises Christopher that the ransom drop was recovered and given back to Madison's father, Christopher is enraged, and soon visited by a Russian mobster giving him one week to come up with the $15 million for a weapon that Christopher plans to pass of as his own.
While Tanner does not believe that the pampered heiress is on the up and up, as he gets to know her, he starts to develop feelings for her, and is surprised when they are returned. But Christopher will stop at nothing to bring Madison out of hiding so that he will have enough cash to appease his creditors, including her own father's health. As he plays on her fears for her father, doubts about Tanner come to light and take her on a collision course with danger.
