BBC One has booked the show "The Split" in the past, while Sundance meijubar.net TV announced on TCA that it will work with BBC One to shoot the show. "The Split" is led by Amy laureate Abi Morgan. It tells us that in this fast-paced world, three sisters Hannah﹑Nina and Rose are divorce lawyers. Hannah and Nina lead divorce and family law lawyers in rival companies. Only the third sister Rose is still looking for her place. At the same time, the three sisters and their mother's father/husband Oscar, who had been absent for 30 years, reappeared, causing their lives to collapse.
