The Equalizer
9pm, Sky Witness
This reboot of the 80s crime-fighting classic sees Queen Latifah bringing some righteous swagger to the part of Robyn McCall, a mysterious former CIA operative gone rogue but using her powers for good. From one perspective, McCall is a single mother, raising her daughter. But she is also a modern-day Robin Hood; a guardian angel of the exploited, powerless and downtrodden. In this opening episode, she intervenes explosively on behalf of Jewel, a teenager accused of murder and on the run from an organised crime gang.
