Inside the O'Briens

Joe O'Brien is a Boston cop; his physical stamina and methodical mind have seen him through decades policing the city streets, while raising a family with his wife Rosie. When he starts committing uncharacteristic errors - mislaying his police weapon, trouble writing up reports, slurred speech - he attributes them to stress. Finally, he agrees to see a doctor and is handed a terrifying, unexpected diagnosis: Huntington's disease.
