The CEO of Britain's biggest nightclub chain, which includes well-known brands Oceana, Liquid, and Lava and Ignite, goes undercover in his own business. He's confronted with the results of cheap drinks promotions, but also meets dedicated medics and cleaners. In 2011, an accident at a Lava and Ignite venue resulted in the deaths of two customers and, with £100m debts, Luminar Group Holdings went into administration. A group of investors, led by 51-year-old nightclub veteran Peter Marks, bought certain nightclubs from the administrator, convinced they could restore the name Luminar to its former glory. But six months on some venues are struggling to attract customers in a recession. Peter goes incognito into the clubs to learn more about the company.
