Star of acclaimed series `An Idiot Abroad', Karl Pilkington, returns to television in his first scripted comedy series `Sick of It', a collaboration between himself and long-time comedy partner Richard Yee. Karl plays Karl, a middle-aged taxi driver in Ladbroke Grove, London, who, struggling to get by and feeling down in the dumps after a recent break up, discovers a grumpy and misanthropic internal voice that says what Karl really thinks. The voice often tries to guide and help Karl, but just as often dispenses criticisms and expounds his unconventional and offbeat views on life, often leading to less than desirable outcomes.
