The multi-award-winning and critically acclaimed hit comedy starring David Mitchell and Robert Webb continues its new fourth series. At the annual JLB conference in Kettering, Mark’s (Mitchell) boss, Johnson (Paterson Joseph), tells Mark he has to give a presentation in front of the entire board. If it goes well, Mark gets a promotion. If he fails, it’s instant demotion. And Johnson takes a shine to Big Suze (Sophie Winkleman), making Jeremy (Webb) an indecent proposal: £530 to let him sleep with his girlfriend. Jeremy can’t believe it but, of course, accepts. But Big Suze is horrified and immediately dumps Jeremy, and starts going out with Johnson. Jeremy is distraught.

Back in Kettering, Mark’s preparation for his presentation is going terribly. He is totally stressed out and has systematically abused all his workmates. To make matters worse, Johnson invites him out to a strip club, where Mark gets into an argument with a stripper performing a sexy lap dance for him. Will Jeremy win Big Suze back? And what happens when Mark decides to run away from the big presentation and hide in the bushes?
