The students’ ball brings back to life the lives of four friends: Salud, Clara, Àngela and Rosa and a transcendental moment, the ball of 12 May 1956, a date that was to mark them forever and ever. Time has passed and, despite the promise of meeting again, they are no longer the girls of 1956, they have grown up and have become different people, often with lives that are far removed from those they had led years before.
The year 2006 marks the fiftieth birthday of the ball that year that passed into the memory of the four friends, now reunited, looking back on the past they lived together.
