In a small Connecticut fishing village known as Watch Hill, walking on the beach at sunset has become a rather enjoyable pastime for Wayne Minor.
Watch Hill is not a very big village and, in fact, it is situated on a small island. It is a very peaceful setting until several mysterious Black Orchid blooms are found on the beach. Suddenly, the residents begin to die one by one, as this quiet town becomes a place of terror.
Everyone begins to wonder where the blooms are coming from and who is behind leaving them for the residents to find.
Nobody is safe from the deadly blooms. Even the police baffled and begin to die. One police detective is so angry that his fellow officers are being tortured and killed that he vows to find the killer or killers no matter what the cost.
