When an unusual handwritten letter arrives at Nelly’s office, she identifies the handwriting as belonging to her childhood friend Dahlia, claiming her boyfriend Blake is being unfaithful. Determined to help, Nelly wants some answers and rushes to Blake’s home only to find his dead body. When Dahlia becomes the prime suspect, the new, handsome Detective in town, Michael Hogan must work with Nelly to prove that her childhood friend is not the killer everyone believes her to be.
