Photojournalist Lena’s career soars when she captures the gruesome victims of the “Snow White Killer” who stages corpses artistically. When her sister’s friend becomes the latest victim, Lena hunts the murderer alone.

When Lena falls for Paul, she suspects the murderer might be closer than anyone imagines.
