Luc plans a surprise party for Carine's birthday. When Cameroonian refugee and pen pal Innocent shows up unexpectedly at Luc's door, he must find a way to politely send him away.

Now Innocent has moved in with the uncles, Luc discovers that his dog is, in all likelihood, a racist. In addition, Innocent's presence hinders Willy in his work as an artificial turf salesman. Innocent still does not feel he's welcome.

Sunday, Luc practices on his flight simulator, but Carine wants to do something nice. Willy needs rest, but doesn't want to blame it on his old age. Meanwhile, Innocent wants visit their mother in the retirement home.

The uncles discover that Innocent keeps all of Luc's letters within close reach of Carine, but that some of the outpourings in those letters wouldn't make her laugh. The uncles devise a plan to avoid an escalation.

Luc is forced by the unemployment office to work in Carine's supermarket. Innocent is waiting for his residence permit and feels useless. Now it is the ideal opportunity for Willy to hire him as extra work force.

It's D-day. The whole family accompanies Innocent to Brussels where he must go to plead his case with the immigration department. The uncles go to great lengths to prevent him from using Luc's letters as evidence.

After Innocent's expulsion order, the uncles organize a benefit: 'Innocent Must Stay'. The Persyntjes are pulling out all the stops. Fabienne makes frantic efforts to win Anke back.

It seems to be end of story for Innocent. The whole family goes to great lengths to make sure he can stay, but he won't play along with all of their schemes.
