At a parents' evening, ambitious tax official Hugo meets Marius, a mobster who's just been released from prison.

Marius finds out that he has a massive tax debt on top of his other money worries. Hugo tries to stop Suus spending time with Chrissie after he saves Marius's life during a shooting.

Marius meets up with Abdu to find out if Wally was behind the attack. Meanwhile, Hugo organises a meeting between his daughters and his girlfriend Hannah, but Laura is hostile.

Hugo doesn't know how to refuse Marius's request for help, and his anxiety gets worse when he goes on Suus's school camping trip only to find Marius and Kitty in attendance.

When Marius finds the missing Suus, Hugo is so grateful that he agrees to help Marius sort out his taxation problems, even though he is still worried about becoming involved.

Hugo insists that Marius go into hiding while he looks at his financial problems. Meanwhile, the police are taking an interest in the odd friendship between a tax official and an ex-con.

Under pressure from Wally, Abdu forces Kitty to reveal Marius's hiding place. Hugo and Kitty try to locate Van Galen's attorney as he might have a lead on the lost money.

Marius escapes with barely a scratch on him to the home of Kitty's parents. Kitty gives valuable information to Hugo, and the police interrogate Hugo again asking why he has files on Van Galen.

Abdu is apparently willing when Marius asks him to help find another hiding place. Hugo, who is hot on the money trail, freaks out when he realises the police have been tapping phones.

Hugo is desperate to bring his dangerous venture with Marius to an end after the money is found, but the situation comes to a dramatic head at Suus's ninth birthday party.
