A new comedy series for Channel Four tonight, written and starring comedian Roisin Conaty which tells the story of hapless 30 year old Marcella as she tries to navigate her way through the world around her with the help of friends, a life coach and a driving instructor. It's Marcella's birthday and she's determined to turn over a new leaf, but after an awkward run-in with a childhood enemy, a few white lies, one drink too many and some dubious advice, her fresh start doesn't quite go as planned. All sounds a tad bit cliche doesn't it? But look, we'll give it a shot.
