When an arsonist sets a series of fires hotter than anything the local firefighters have ever seen, Finn McLain becomes the prime suspect. But all he's trying to do is find out which of his fellow fire wizards is really guilty. Niki Hansen is a firefighter who rushes into fires to save those trapped inside but always remains unscathed. She wants nothing more than to find out who's setting these fires that burn everything down to ash, including the bodies of the victims. When Finn sees Niki, he realizes she may be the first female fire wizard in a century. When she accuses him of setting the fires, he convinces her he's innocent. But will he be able to convince her to embrace her unique abilities? While they try to find out who's behind the fires, they end up starting a few fires of their own.
