The Threshold: A North Indian couple, in their early 60s, at their mountain retreat. Their son has just gotten married, a reception has ended and all the guests have left. She chooses this moment to tell her husband that she is leaving. What follows is an endless day: the avalanche of this long-gathering decision and what it means to a decades-long relationship. Fragments of conversations, silence and chaos, as nostalgia mingles with menace and tenderness with cruelty. What will they succeed in rescuing against the landslide of memory and emotion?
