Jaisus Kev, some really thick commenters below, inna!? It's about how boys often feel very deep and powerful affection for each other, but are forced by a homophobic society to hide those feelings behind a mask of risky, sometimes violent bravery. It is a masterfully done 3 minutes of film.
I would have to say that the brilliance of this film is in its subtlety. A lot of gay shorts like to provoke the viewer by extreme use of sexuality, this one however focuses on intimacy, and, on the power of attraction that erupts in seconds without reason. Just like, real life.
