Tim is a youth who is discovering his sexuality, he's a dreamer who'd love to go to outer space. His older brother Julio would seem to have no such problems - he's masculine, good looking and confident. A soldier, in fact.
Julio's return provokes turmoil in Tim after he watches him in the lavatory pleasuring himself. This leads to a secret moment of ecstasy for Tim too.
Afterwards there's a subtle change in the brotherly dynamics. Julio senses something is wrong and Tim can't hide it.
Tim takes his chance at an incestuous relationship. I can't say I'm convinced as there is such a societal taboo against this.
We are left to ponder what becomes of the family relationship afterwards.
