The big night has arrived. Finally, the choir will get to show what they have been practicing all autumn - with all their loved ones present.

The concert is approaching and the choir members are really feeling their nerves. But the dress rehearsal at Chat Noir makes the nerves anything but calmer.

The choir will be this year's winners of the "Dementia Award" in Oslo, and will perform for the first time during the award ceremony in Oslo Concert Hall.

The choir will sing on the opera roof and Bobbysocks will throw a party. To everyone's great sorrow comes the news that the choir has lost one choir member.

A research team follows the choir to document what kind of effect the choral singing has. Program leader Ingrid travels to Trondheim to meet Nobel Prize winners.

The choir members meet for the first choir practice. It is an excited group, where the youngest is only 48 years old. What will the choir sound like?
