Tells the comedic story of aging partners Freddie and Stuart, two men who have lived together in their Covent Garden flat for nearly 50 years. Freddie was a budding actor and Stuart worked in a bar when they first met, but their careers are pretty much over and their lives now consist of entertaining their frequent guests, making sure that their aged dog Balthazar is still breathing, and hurling caustic insults at each other.

The penultimate season of the hugely successful, long-running drama introduces a host of new characters. There's Beth Bailey, a brilliant ex-mercenary who was posing as an Eastern European prostitute when she ran into the team. Dimitri, an ex officer in British Special Forces, has been recruited for his skills in fighting terrorism on the front line. And finally, data analyst Tariq has been fast-tracked through the system.
