To her clients and colleagues, Iris is a therapist in a city psychology practice. But to the police and fire services, she is the Fire Lady - a profiler of arsonists. After a troubled young man burns down her office, Iris just wants a quiet life. But her peace is shattered when a bomb goes off at a local school.
Called in to help, Iris meets James, delusional and dangerous, and Chuck, a lone investigator tracking a serial arsonist he calls Zorro. As public attacks become more orchestrated and brazen, Iris is soon embroiled in the investigation - as a profiler and as a suspect, and in serious doubt about her own sanity.
