When Kate Kingston loses her job as a probation officer, she decides to start her own business, helping police to monitor criminals in a house arrest program. After sinking every dime she has into equipment and supplies, Kate gets a break, her first client, but why does it have to John Mackowitz, a former high school crush with the uncanny ability to get under her skin.
John Mackowitz has dedicated his career to upholding the law. A by-the-book police officer, John is shocked when he finds himself portrayed as a dirty cop and accused of selling confiscated drugs. After his partner is shot in the line of duty, John knows he has no choice but to find the people responsible, even if he's technically not supposed to leave the confines of his house.
Kate knows that the only way her program, her livelihood, and her future can survive is if she can keep Mack in his house. He knows the only way to find justice is to go out and find the truth. And they both know getting involved is a bad idea, but as danger hits closer to home, they find the only people they can trust are one another.
