In an interview on the Channel 4 site, Jesse Armstrong and Sam Bain explained that the first episode would pick up immediately after the final scene of the sixth series, with Mark (David Mitchell) and a pregnant Sophie (Olivia Colman) driving to the hospital.
"We thought long and hard about whether we should join the show three months down the line or whether we should directly continue it," explained Armstrong. "And in the end we decided that we've seen a lot of tense moments in Mark's life, but seeing him at the birth of his child felt like something we just couldn't afford to miss."
"There will be a new love interest for Jeremy as well," added Bain. "We haven't cast that yet, though."
The pair also admitted that they were unsure how long the sitcom would continue, with Bain insisting that the writers "need a break".
"It feels like... we might both throw up if we had to think about writing the next series right away," agreed Armstrong. "[But] I don't think we could think about it stopping."
Peep Show will return to Channel 4 in November.
