Jen (Katherine Parkinson) who successfully interviewed for a big company thought she had won the jackpot, but she was assigned to the IT department in the basement. There were only two people in the department, Moss (Richard Ayoade) and Roy (Chris O'Dowd), two computer experts and common sense geeks. Jen, who knew nothing about computers, pretended to be proficient, causing a lot of jokes. Jen and the IT geek duo unexpectedly got along well, always making some ordinary things out of control, making people laugh and cry. The boss of the company (Christopher Morris) would appear from time to time and perform hilarious stories with them. A unique British humor story was staged in the IT department.
