Cases of 'rent for sex' in the UK are on the increase, where landlords offer free rooms in their properties in exchange for 'sexual favours'. Investigative journalist Ellie Flynn goes undercover to get a closer look at this issue. Armed with undercover cameras, she meets landlords who post these ads to find out what they really expect in exchange for rent. The landlords she confronts protest that what they're doing is acceptable, contrasted with young women who have taken up these arrangements and talk about how much consent they felt able to give when the alternative was a life on the streets. Despite laws that exist to criminalise this practice, Ellie asks why there doesn't seem to be anyone doing anything to prevent it. From police forces to the Ministry of Justice, she uncovers a vacuum of responsibility that currently exists.
