At work Nina is known as the Ice Queen as her frosty demeanour makes her colleagues think she's equally cold in bed. But what they don't know is that she spends her free time acting out sleazy scenarios with her boyfriend Andrew in which she's a prostitute & he's a punter. But when Andrew starts inviting his less-than-respectable friends to join in their games things begin to get strange & Nina finds herself being drawn deeper into London's seedy underworld where everything is for sale & nothing is what it seems.
