“Dear Past Me,” is a short film focusing on a boy named Alex. 
Fast forward many years into the future (2050), Alex lives in a water-scarce Singapore, where life is hard. He writes a letter to his present-day self (2021), reflecting on how he regrets not taking action to save water wisely, and the consequences he is facing in 2050. Will this message reach 2021 Alex? Can the outcome be reversed?
