The Echo explores the life of Bijan, an Iranian man living in the capital, Tehran. Instead of putting importance in his national identity, Bijan identifies his identity from a humanitarian outlook first and foremost. Rather than talking about collective Iranian identity, the film focuses on the relationship between individual identity and society. In order to escape from the expectations of society Bijan spends a great amount of his free time during the night where he feels that he can be more himself. We follow Bijan's life at night while he goes around different places in Tehran. We slowly get an insight into his relationship to society and how he tries to avoid society in some aspects.
Bijan then sets out on a journey to Armenia in order to participate in a Rainbow Peace Gathering, a meeting of people from different cultures and backgrounds with the goal to share ideas, skills, love and power as a community. While participating in the social life, the interacting with new people and the living condition helps Bijan to become more aware of his identity traits and we slowly get to know him in more depth. However, Bijan slowly distances himself from the community. At the end he finds the greatest peace not by belonging to a group, but rather by spending some time for himself. With peace in body and mind Bijan reaches a state of self-realisation and shares his opinions on the relationship between happiness and the surrounding environment.
