Chicago, 1998. Harrison and Katherine are both struggling. Harrison’s wife recently left him and he gave up a challenging career choice for a safer one as a Math teacher. Fourteen-year-old Katherine’s school cannot see past her cerebral palsy, so she’s not allowed to take “normal” classes. Schism begins when both characters reach breaking point: Harrison is mid-suicide attempt when Katherine breaks into his home to appeal for his help to move into his Math class.
