In poker, "ALL-IN" is the act of risking everything to double or triple your winnings. A choral scene has the same risk (chaos) and the same potential! A work on the very difficult art of not stealing the spotlight, on the unconditional acceptance of collective choices, and on the group mind, to create a single character made up of many people. Training to act together with listening, harmony, and complicity for a victory of great visual and narrative impact.
