In each stand-alone episode, four people close to one another draw names and anonymously write to the selected person a thoughtful yet totally honest letter outlining what, in their opinion, needs to be changed in order to improve and transform for the better the life of the recipient. For one week, each "reader" must follow all the rules and instructions outlined in the letter - culminating in a dramatic and emotionally charged meeting where the authors of each letter reveal themselves to their best friends.
