A demon is coming to Saint's Grove. Luckily experienced demon tracker Ally lives in town and picks up the demon's trail. Hot on his cloven hooves is a tracker from a world parallel to hers, a man by the name of Brandon, who just happens to be the other universe version of her sleazy ex-boyfriend, Cole. As if things weren't bad enough, the demon is after a witch-crafted relic known as The Heart, with which he plans to open the gates of hell and enslave all of humanity. Ally and Brandon must race against the clock to destroy the threat to her world. Working together, the two are at odds. Ally can't help but be drawn to Brandon, but she's not sure trusting him is worth the risk of a broken heart. Brandon knows Ally has been hurt before, but can he convince her he's worth taking a chance on?
