21 April 2015. Thomas, 38 years old, finds himself in front of the family home where he spent the best years of his childhood. As he ventures, nostalgically, into the now abandoned house, his deceased grandmother appears to him and offers him a deal: to relive the last twenty years of his life!
On April 21, 2015, he will have to show up at the same place where he will then have a choice: go back to his old life or stay in his “new” life. Thomas accepts. Projected twenty years back in time, he is 18 years old again, and has 38 years of hindsight and experience to not reproduce his youthful mistakes.
But going backwards without making a mistake is not that simple…
Faced with the experiences of his younger years, Thomas will have to make new choices. Will he have the courage to change the course of his life? Will he forget his past, his wife and his children? Will he be able to avoid the chaos caused by the flapping of the butterfly’s wings?
