The story follows talented carpenter Whitney Whitaker and her cousin Buck, who are interested in a historic building on the real estate market – an old fire station in the Germantown neighborhood. As they begin the renovation work, Whitney is approached by her neighbor Joanna Hartzell for help. Joanna is struggling with the deterioration of her inherited home, as her seven siblings refuse to make any repairs. Whitney and Buck take on the rundown property, but when Joanna suddenly collapses and dies, Whitney becomes suspicious. She suspects that there is more to the incident than just a tragic accident. Together with Collin, she tries to piece together the clues and uncover the true murderer.
