The unloved, ignored, socially-awkward Roy and Moss make up the IT department of Reynholm Industries. Their world is shattered by the arrival of a new relationship manager, Jen.

The team face their first test during Reynholm Industries' so-called `War on Stress'. The office is on fire, Roy has a sudden attack of kleptomania, and Jen's new shoes are two sizes too small.

Jen has a new admirer, but his romantic gesture goes horribly wrong when Jen's inability to tell the truth results in a very public humiliation.

Everyone is wandering what is behind the mysterious red door in the IT department and what has happened to Moss's new mug. Also, why Roy is in danger of becoming known as a `desk rabbit'.

Moss goes to extraordinary lengths to help Jen escape the unwanted attention of potential suitor, Bill Crouse. Meanwhile, Roy is busy trying to escape the attentions of an admirer of his own.

Jen explains that she is subject to very powerful mood swings around a certain time every month. When Moss and Roy start to display similar symptoms, it leads her to a terrifying and bizarre conclusion.
