Plot

An autistic child whose mother desires to have him treated at the Harbor Neuroscience facility is instead raised by his father, a military PsyOps agent who refuses to enroll him. When the mother leaves the family, unable to cope, the father trains him and his brother in martial arts, encouraging the child to acclimate himself to triggering stimuli rather than avoiding them.
