On March 3, 2010, single mother Barbara Hamburg was found violently murdered near her home in the upper middle class enclave of Madison, Connecticut. Investigators speculated her murder appeared to be a crime of passion, but without enough evidence, the case grew cold.

Over the course of 8 years, Barbara's son, Madison Hamburg, interviewed his family members and many others, longing to learn more about his mother and gathering evidence in hopes of solving her murder, sending him into a deep web of buried familial secrets, connections to shadowy criminal figures, and the uncovering of years-old resentments in his deceptively serene hometown. While Madison wrestles with troubling revelations about his mother, the most unsettling conflict comes from Madison's obligation to bring into question those inside his community and members of his own family.
