The new season of Call the Midwife is about to take on a new impact.

On Sunday, Mirror released details on the anticipated Christmas episode, which will air this holiday season and delve into a South African mission. This will lead into apartheid as friends help the mission during a time of racial segregation.

South African casting director Christa Schamberger gave more details on the episode and the controversy that surrounded this era back in the 1960s.

"Because the midwives are at a clinic deep in a rural area, they see the drastic effects of apartheid- with absolutely no facilities for black people," Schamberger said. "The government was not supportive of mission hospitals, so they depended on donations as well as their overseas connections. Babies had no incubators or any neat and tidy sterile theatres."

With this episode being centered around Christmas, it will not take on the idea of Santa Claus coming down the tree. Instead, it's going to take on something much more intimate.

"Producers have gone through a lot of trouble to make it accurate and authentic of the time," the casting director said. "We are not talking about people under big Christmas trees, surrounded by presents. We are talking about people grateful for a good meal, for family, friends and any support."

In a previous report from Xpose, screenwriter Heidi Thomas dished on the success of the series and how there's a good chance it won't leave television anytime soon.

"People have been saying, 'Oh, it'll all end when the pill comes in' as though no more babies were ever born again and the entire world was sterilized," Thomas said. "Call the Midwife could run for another 50 years and we could be covering the issues of today."
