Mom, daughter clash in ‘Sins’

The general gaze toward Vancouver can inspire some interesting counter-programming. What better time to air a difficult drama about a recovering alcoholic and her damaged, embittered daughter?

“Sins of the Mother” (Sunday, 5 p.m., Lifetime Movie Network) stars singer/actress Jill Scott (“The No. 1 Ladies’ Detective Agency”) as middle-aged Nona, who struggles to stay sober.

Her upbeat affirmations make her a hero to friends, including her sponsor (Mimi Rogers). But when her graduate-student daughter, Shay (Nicole Beharie), returns home, both women have to confront a bleak shared history.

•“Invasion of the Giant Pythons” on “Nature” (Sunday, 7 p.m., KSPS; 8 p.m., KCDT/KUID) chronicles the unfortunate introduction of Burmese pythons into the Everglades as pets, many of whom were abandoned in the wild as they grew.

Now these creatures – 18 times larger than the biggest native snake – are slithering to the top of the food chain in Florida’s precariously delicate ecosystem.
