After witnessing an uncontrollable blaze burn her family's pizzeria to the ground when she was just 11 years old, it's no wonder that Reena (Alice Witt) decides to become an arson investigator. Now, years later, our all-grown-up heroine decides to visit the old neighbourhood, where she finds true romance with a hunky carpenter named Bo Goodnight (Matthew Settle). But Reena is swiftly knocked off her cloud nine when she discovers that a psycho connected to her past has resurfaced to wreak havoc in her life. It turns out this villain has an unhealthy obsession with torching things (or people!) who are near and dear to Reena. Now she must use her sleuthing skills to snare this pyromaniac before her life (and love) go up in flames - literally!
