从前的香港，大街小巷也有小摊档出售一包包白兰花，子健的母亲最爱白兰花的香味，其实儿时的子健不太明白。然而当长大后的子健遇上意外，昏迷卧床，他回忆从前种种，甚至经历回归母体的奇幻过程；他重新感受母亲对他的爱和期望，亦似乎明白了白兰花的意义。于是，同样处境下，如果能重来一次，子健对母亲的态度改变，并选择以不同的方式相处，或许就能改写人生。

Once in Hong Kong, some stalls on the streets sold bouquets of white Orchid. Zijian's mum liked the fragrance of white Orchid very much. Zijian didn't know why then. He grew up. One day, he was injured by an accident and went into coma. Lying on the bed, in his deep dark dreams, he had his childhood back, he even experienced a fantastic return to the womb of his mother. Once again, he felt mum’s love and expectations on him. He had a vague clue why the white orchid was so important to her. Had he had a chance to go back in time, Zijian would change his attitude towards his mum and accompany her in a different way, and, he may be able to rewrite his life.
