玛蒂离家多年，弟弟担负起照顾家中重病母亲的责任。无数的日子过去，玛蒂的房间仍维持原样，时间好似因思念而静止在她离家的那一刻。有天玛蒂突然返家，即便当年的不满情绪依然存在，面对母亲即将不久人世，过往相处的回忆让她选择重拾亲情的温暖羁绊。本片为导演首部长片作品，取材自身经历，以充满诗意的画面诉说对母亲的情感。

Crushed by a messy unrequited love, a young queer poet, through the confidence of their best friend and the truth of their art, finally reckons with their own emotional baggage (or, 'boulder'). The film oscillates between 16mm narrative compositions of everyday life and Super 8 montages which imagine the world of their poetry.
