Spy

Tim is in a custody battle with his ex-wife, when he quits his job. He applies for a job as a civil servant doing data entry, but discovers during the job interview that he has been offered a job as a trainee spy for MI5.

During a training exercise, where he is to collect a bag of intelligence in an empty building, Tim comes across a homeless Eastern European man who falls during a struggle. Tim is viewed as a hero in the public eye for saving him, but the Examiner orders Tim to kill him, a mission which he is reluctant to carry out. Despite this, the man ends up electrocuted thanks to the faulty wiring in Tim's house. In the meantime, Tim also has to deal with a social worker named Paula (Cavaliero) to improve his relationship with Marcus. However, he realises Paula is insane, and she tends to think they are in a relationship.

Tim learns how to computer hack, and decides to lower Marcus's school grades. His friend Chris (Baynton) also uses these skills to alter his bank details and gain money. Marcus and Chris develop a bond, but Chris is ultimately caught by the authorities for hacking the bank. Paula continues to make unwanted advances towards Tim.

Tim has a large interest in joining Marcus' lavish book club, but is prohibited from taking part. Unknown to him, Marcus actually runs a different kind of club, and the "book club" is really a cover. Eventually, Marcus allows his father to join the club, just as he decides to end it. Meanwhile, the Examiner demonstrates his lie-detecting skills.

Tim swaps blood samples with the Examiner. However, it is revealed there are drugs in the Examiner's system, and Tim is forced to attend a drug intervention programm, run by none other than Paula. She further embarrasses Tim by having his family made aware of his attendance in the intervention. Paula forces him to read that he has feelings for her, but he refuses after it is emerged he has feeling for Caitlin, a colleague at MI5. Furthermore, ex-wife Judith informs Tim of a child custody hearing so she could keep Marcus. Marcus meanwhile, is given a taste of power in his school, which he abuses.

The custody hearing is not going in Tim's favour, until Chris steps in as his lawyer and wins the case, on the condition that Tim confess his feelings for Caitlin. Judith sleeps with the incompetent judge in order to win the case, however he has already sent off the case. Tim, going to confess his love to Caitlin, finds her kissing her presumed dead fiancé, an American CIA agent, Portis (Maynard). As their final training exercise, the Examiner creates a false security breach in MI5. At the conclusion of the exercise, Tim becomes an official MI5 agent.
