On a summer night in 2009, three lives intersected in one American neighborhood. Two people newly in love --- Teresa Butz and Jennifer Hopper, who spent many years trying to find themselves and eventually found each other --- and a young man on a dangerous psychological descent: Isaiah Kalebu, the son of a distant, authoritarian father and a mother with a family history of mental illness. All three paths forever altered by a violent crime, all three stories a wake-up call to the system that failed to see the signs.
