Still under pressure to impress, will Alex's musical mates put up with his ridiculous requests? John Oliver secures a performance from Imogen Heap, who appears with tribute band The Horne 'Selection'.

A lonely Alex tries to mend his friendships and calls on celebrity psychologist Ken to help get the band back together. With Thora back on set, can they make their final episode the best one yet?

Struggling with his newfound fame, the pressures of filming live from his family home, and a subsequent lack of money, Alex is determined to prove to the nation that he's a credible leader of his band, while trying not to be overshadowed by the real musicians he works with. In the opening episode, following an unsuccessful TV appearance, Alex is determined to prove that he's a credible musician and bandleader. Meanwhile, production extraordinaire Thora (Desiree Burch) notices that acclaimed multi-instrumentalist Reggie Watts is touring the UK and books him as a guest on The Horne Section TV Show. And when Channel 4 exec Ash (Georgia Tennant) commissions a new programme, the World's Strongest Musician, Alex sees his chance to prove himself to the nation and enters the band to compete on his behalf. A shock twist in the final means that The Horne Section could be eliminated, but is there someone in their midst who can save the day?
