On the eve of the new football league, Boma is not lacking in ambition: this season he wants his team to play champion! For that reason, he is forced to pull through a few changes. Xavier, the old dean of the team, gets replaced by Jean-Jacques, a talented goalkeeper who once played for Barcelona. The women are furious and want to take action. Meanwhile Fernand keeps bullying his neighbors. This time he is planning to sabotage the soccer field.

Boma and Ronaldinho want to surprise Goedele for her birthday: Boma is planning to formally adopt the son of his girlfriend. Goedele has her doubts and sets a first condition: Ronaldinho must pass his astronomy exam. Boma takes up the challenge, but with his own nature and the playfulness of Ronaldinho it is not easy at all. Carmen is inspired by Boma's plan and arranges a similar adoption. The 'lucky' guy is ... her dog Nero.

Boma decides to release the club anthem on single, to bring the popularity of the now always winning Champions even further. He starts looking for a famous artist to spice up the song. The other Champions also believe that they should be able to sing and launch a competition held in the café. Fernand sets himself up as manager of Carmen and does his evil best to sabotage the other participants.
