London calling

“Ripper Street,” more proof that the Brits do detective stories better than we Yanks, returns for a second season of intrigue in East London, 1890. New threats include a female gang going after industrial tormentors, subversive cult Svengalis and a mad eugenicist who stalks circus freak shows for prey. 8 p.m. Sat., BBC America

Image makers

Oprah Winfrey salutes Nelson Mandela during “The 45th NAACP Image Awards,” an event that brings together a wide range of talent, including Idris Elba, Vin Diesel, Nia Long, Ben Vereen and Ed Asner. Anthony Anderson has hosting duties. 8 p.m. Sat., TV One

Father knows best

It’s always risky to revolve a sitcom around a character with a physical disability, but “Growing Up Fisher” manages to walk the tightrope thanks to a sentimental script by DJ Nash and a strong performance by the always reliable J.K. Simmons, playing a man who doesn’t let his blindness get in the way of being a strong role model for his son. 9:38 p.m. Sun., KARE, Ch. 11
