Snowfall
10.30pm, BBC Two
The crime series on the 1980s first-wave crack epidemic in Los Angeles, co-created by the late John Singleton, reaches its third season. Young dealer Franklin found himself facing a murder charge at the end of the last series, and this double bill opens with his family betrayals put to rights and his gang back on the streets. But his time away in prison leaves him reckoning with the changing nature of the game, while Teddy searches for new supply routes. It’s a hard-hitting start as the police close in on the operation.
