In a story that looks dramatic and controversial as the story tells of a woman named Sam, a woman who almost suffered from accumulated debt in her life, which could change everything in her life. This series begins with events where Sam was forced to work for one hour on the minimum wage as a cleaner in Canary Wharf in hopes of restoring balance to her material and moral life. By accident, Sam discovers the lucrative and illegal stock market information in the office you clean, which may change everything completely.
You can't help rooting for them in the absurd scene where Sam balances on a desk to plants a microphone in the ceiling of the insider dealer's office and cheering as their 50 investment blooms into 500.
Cleaning Up groans under the weight of contrivances, but what will make viewers return next week, despite the plot being as daft as a loo brush, is Smith.
Smith exhibits the skill that has made her one of this country's favourite actresses, but it is yet another case of how she continues to be typecast in working-class roles.
This is completely preposterous, of course, but the series also comes with a stickily sentimental, lightly Dickensian atmosphere that might be just right for this time of year.
