The six-part documentary series “Blackboard Wars” (9 p.m. Saturday, OWN) follows a new superintendent, principal and faculty as they try to turn around the worst performing high school in New Orleans.

The students at John McDonogh High School are used to gun violence, drug dealing, rampant promiscuity, homelessness and pregnancy. Education maverick Steve Barr and Principal Marvin Thompson set out to change a school’s culture of failure and their students’ low expectations, while fighting local community activists who fear and resent any outsiders.

• After a handsome author (Cameron Mathison) and his wife (Annie Wersching) discover that they cannot conceive, they decide to allow his faithful assistant (Amy Scott) to bear their child in the 2013 shocker “The Surrogate” (8 p.m. Saturday, Lifetime). What are the chances that she turns out to be a homicidal maniac?
