Please help me find the title of a movie I saw some 10 years ago on the French TV5 over the satellite. Possibly it is a TV release.
It was about a girl aged about 13, black haired, probably on a vacation with her younger brother and another girl about the same age.
I remember a scene where the two girls were riding on a motorbike and without getting off they changed their shirts.
Unfortunately I don't understand French
Please help!
