DRAMA Cleaning Up, 9pm, ITV
If you have a gambling addiction, it's probably not wise to get a cleaning job in Canary Wharf, where you'll have endless access to stock market information. Then again, it makes for an excellent stage for a primetime drama, so we'll just ignore main character Sam's (Sheridan Smith) folly. Fuelled by her addiction, she convinces a friend and co-worker to engage in a little insider trading – a highly illegal and potentially devastating practice. The high-rise life of the bankers who work in the same office as Sam are in stark contrast to her suburban everyday, where she spends most of her time in the role of a mother. What could possibly go wrong?
