The show, executive-produced by former TNT star Kyra Sedgwick, will focus on the life of surgeon Dr. Kathryn Russo. She's a born skeptic, but will start investigating supernatural cases -- hauntings, reincarnations -- after the death of her teenage son.
Beals, whose previous television credits include The L Word and Mob Doctor, teased the news on Twitter over the weekend.
"Well, I just got some good news...#standbyfordetails," she wrote.
