Presenter George Lamb and a group of doctors advise people with excessive lifestyles how to become healthier and avoid serious illness. 27-year-old management consultant Lynsey Carratt seems to have it all - a good job, a nice place to live and a good social life. But this urban good life could soon be over unless Lynsey gets a grip on her partying lifestyle. Poor timekeeping and killer hangovers are threatening her job and unless she calls a halt on the post-clubbing house parties for which she's become renowned she could lose her apartment in a swish London gated community. Growing up in Hull, Lynsey's life was under control and it was only when she moved to London in her mid-twenties that the temptations of glitzy parties and omnipresent cocaine proved difficult to resist. Lashings of wine and vodka, drug binges and a packet-a-day cigarette habit have left Lynsey exhausted, unable to concentrate and in imminent danger of total burn-out. An eye-popping living autopsy brings Lynsey's parents face to face for the first time with the true reality of their daughter's bad habits, and then Lynsey clashes with her live-in medic Dr Ahmed, a teetotal GP whose experience as a prison doctor means he should be used to dealing with strong-willed women. But the coke habit proves hard to crack and with her career and home life on the line Lynsey's life is in danger of spiralling out of control.
