Peep Show features Mark and Jeremy, two flat-mates living in south London. Mark is a credit manager and the more financially successful of the two, often pessimistic about life and anything to do with Jeremy's next big 'idea'. Jeremy rents Mark's spare room and usually has a much more optimistic and energetic outlook on the world than Mark. His self-proclaimed talent as a musician is yet to be recognised, and he is seen as a lazy waster with dodgy friends and not as popular or attractive as he would like to think himself.

In series 6 Mark and Jeremy are still sharing a flat in post-credit crunch Croydon while there is a whiff of desperation surrounding them. Having discovered that Sophie is pregnant they have to face up to the possibility that either one of them might be a father. How will this effect Mark's pursuit of Dobby? And will it help or hinder Jeremy as he falls for his dream woman, dope-dealing-musician-activist Elena?
