Following the brutal and unsolved murder of his mother Barbara back in 2010, Madison Hamburg returns to his hometown of Madison, Connecticut to piece together her life story. Through interviews with those who knew Barbara best, Madison dives into his parents' divorce and the unsettling details of his mother's life that were kept under wraps.

After Barbara’s sister Conway opens up about her history with substance abuse – which fueled deep-seated familial resentments – she makes a stunning accusation against someone inside Madison’s family that leaves Madison shaken. Conway and Madison’s sister, Ali, both offer their accounts of the morning they discovered Barbara’s body, Madison consults a private investigator to help find evidence to exonerate his loved ones.

With the 10-year anniversary of his mother’s death approaching, Madison leaves no stone unturned in his quest for the truth – despite concerns that his documentary may be doing more harm than good. As Madison presses on, there are surprising roadblocks to his investigation.
