Diana Pellino comes from an overprotective family, a family of cops, with a few fire fighters thrown in. As a cop herself, she has risen through the ranks until she is now a homicide detective. Her latest case is beginning to look like the work of a serial killer. Now though, the murderer has added arson, burning his victims. Having to work with Luke Fontella, the fire marshal, puts stress not only on her case but also with her family when the case seems to lead in directions that may threaten her family. Working with the overbearing, arrogant but very desirable Luke, racing to solve the case before another murder and dealing with the family issues, leaves Diana with more than enough problems. Add to this that the facts point to someone close not being trustworthy, and Diana is left with little choice but to trust Luke who may be the only one who can help her solve the case.
