Hen and Lloyd are the only newcomers at their neighborhood block party, where they meet Matthew and Mira Dolamore. The two couples, who live next door to each other, strikes up a friendly conversation and decide to have dinner together at the Dolamore's home. While in Matthew and Mira's house, however, Hen spies what she believes to be a trophy stolen from a murder victim who was killed not far from her former home in another town. How could Matthew have this award unless he had taken it from the dead man's apartment? She becomes obsessed with the idea that her neighbor is actually a killer rather than just a harmless high-school teacher. Hen, who continues to struggle with her bipolar disorder, doesn't have much credibility in the eyes of either the police or her husband - even when another murder is committed, and Hen is sure Matthew is the murderer. She refuses to be swayed from her theory of the crime. Will her persistence lead to the arrest of a murderer or to her own descent into madness - or even her death?
