Alan stands in a local council election, and surprisingly gets Boyce to help him. Martin accidentally becomes a pimp, Lyndon goes out on a date with Harriet, and Mac discovers that Holly never had that abortion - could he really be a father?

Alan decides to stand for local elections, a feat which he believes can only happen by making his voice less "screechy" and so enlists in the help of a speech therapist, though without much success. He also gets help from Boyce, who hires himself as campaign manager but still finds it difficult to get the public to accept his policies.

Whilst Alan throws himself into his new career as a politician, Martin ends up in a much seedier occupation. He accidentally ends up as a part-time pimp, a role which he throws himself into enthusiastically (even inventing a special pimp walk). However, his career comes to an abrupt end after Karen dumps him and he gets threatened by a full-time pimp.

Elsewhere, Mac's luck finally seems to be on the up when he gets to kiss Caroline again. However, that all quickly changes when Holly informs him that she is has a son and that Mac is the father. When Caroline finds out, she does not take the news well and seeks solace from new flatmate Guy (whilst at the same time trying to fight off the affections of the complementary therapist Jake Leaf). Will she ever get the man that she really wants?
