Madison Avery is a young woman with a huge problem. From her penthouse
apartment, she witnessed a murder in the building across the street, but
by the time the police arrived, the crime scene had been wiped clean.
Unfortunately Madison suffers from prosopagnosia - face blindness - so
even though she had a clear view of the murder, she can't describe the
victim or the killer. With no forensic evidence that a crime was
committed and no description of the victim to match to a body, the
police have no choice but to close the file.
But Shaye Archer doesn't have the same limitations.
When Shaye hears Madison's story, she believes the young woman saw
exactly what she claims, and even though Shaye knows finding the killer
will be next to impossible, she can't turn down the distraught woman.
Especially when she finds out that the killer saw Madison. Soon the
killer turns his attention to Madison, taunting her to heighten her
fear, and Shaye is afraid his sights are set on his next victim.
