Among the many things he has had to deal with are lost passports, people arrested for drug offences and lads being drugged and robbed by prostitutes.Sheila's son Johnny, 38, is in Bangkok's Bang Kwang prison and is five years into a 50 year sentence for attempting to smuggle two-and-a-half kilos of heroin out of the country. Johnny took the drugs in a bid to pay off a debt to a Thai gambling ring and believes that one of the gang tipped the authorities off. He now lives in a 12ft by 15ft cell with up to 30 other prisoners. His mother is allowed one contact visit with her son each year. "Johnny is a wicked boy, he saw a way out of his financial problem. Ha made the biggest mistake of his life, and he's paying for it with his life."Each week 10,000 people travel from Britain to Bangkok and this series takes a closer look at the personal stories behind these journeys.
