Sunday Snowfall 10pm, BBC Two
HOPPING around the various rungs of the drug ladder in 1980s LA, this drama is more a steady slow burn than a compulsive addiction, but it remains a satisfying Sunday night dependable. The path that Franklin (Damson Idris) is on grows darker tonight as, following the beating and robbery last week, he sets out to recover his cocaine cash, and take revenge on the unknown rivals who took it. To this end, his friend Leon hooks him up with a local thug, Karvel, who he enlists to help track down the thieves, leading to some of the most troubling scenes the series has so far presented, and a grim new determination by Franklin to toughen up. Meanwhile, CIA man Teddy begins to get antsy when he and his Contra contact Alejandro line up an arms deal involving US Army rocket launchers. Elsewhere, seeking to throw off suspicion for their heist, Lucia, Pedro and Oso concoct a gruesome plan to frame another member of the cartel, but Oso’s ethics lead to complications.
