Let down by the adult world, teenage brothers Alex and Robin have been left to fend for themselves. Their protective symbiosis has forged a strong bond that’s made Robin completely reliant on the older Alex. That is, until Alex falls in love. Feeling abandoned by Alex, Robin is sent into freefall. Alex blames himself for naively letting his first love distract him from his responsibilities towards his younger brother, and pours all his effort into saving Robin—who may not want to be saved.
