A solar eclipse seems to be interfering with the menstrual cycle of women everywhere and wreaking havoc on their hormones. The result is a need to kill any and every man they see.

Dr. Thea Kait is a forensic scientist with the Seneca Police Department. She is called to the scene of a crime by her friend, Detective Kurt Blas. There’s been a murder… or has there?
