The series is based on the stranger-than-fiction prison break in upstate New York in the summer of 2015 which spawned a statewide manhunt for two convicted murderers, aided in their escape by a married female prison employee who carried on months-long affairs with both men.
After the June, 2015 prison break from Clinton Correctional Facility in Dannemora, NY, Joyce "Tilly" Mitchell is questioned about her involvement with the two men. Months earlier, Tilly enjoys her job at the prison tailor shop, balancing the temptations of David Sweat, a younger inmate, and her obligations to her husband, Lyle. Richard Matt, an inmate with an artistic talent, supplies oil paintings to guards in exchange for special treatment. Ultimately his attentions turn to Tilly. Series premiere.
