The Kyle Files

This time, Jeremy explores Britain's relationship with alcohol. Every day in the UK more than 20 people die from excessive drinking and that number is rising. In 2016 the government's Low Risk Drinking Guidelines were published - but few people seem to be aware of them and even when they are, many don't follow their advice. Jeremy goes out with West Midlands Ambulance Service to see the impact alcohol has on emergency services, speaks to those addicted to drinking, and consults an industry expert on the true scale of the problem.

In the fourth episode, Jeremy probes the private rented sector. More than three million people are thought to be living in properties that are not only unfit for purpose but some are even dangerous. Jeremy goes out with council officers as they visit some of the worst offending properties. He meets tenants living in terrible conditions, confronts a rogue landlord and hears from an organisation fighting for tenants' rights.

Jeremy explores the facial aesthetics industry - because demand for procedures such as anti-wrinkle injections and dermal fillers has boomed, the sector is now thought to be worth a massive £3 billion, yet is almost entirely unregulated. Jeremy meets people who take these procedures to the extreme, hears from a girl who paid the price of a poorly skilled practitioner and goes undercover to put a high street salon to the test - with shocking results.

In the final episode, Jeremy investigates knife crime after the number of people who lost their lives to knives in 2018 reached the highest level since records began. He goes out on a series of raids with the Metropolitan Police to tackle violent crime, hears from the families of those killed and injured in stabbings, meets youths who refuse to put their knives down and visits prison to see if there's another way to tackle the problem.
