Fai is mired in work on a project that appears to foreshadow the wake-up call he is about to receive. Rushing to the bedside of her grandmother, he is shocked to learn that not only she is at risk of being paralysed following a stroke but that her faculties have been compromised by advanced Alzheimer’s. Entrusted with the care of the grandmother’s canine companion, he is confronted with the sad reminder that a man’s best friend has taken the place of absent family members and filled in the emotional void, prompting him to reassess the priorities in his life and make amends for neglecting an endearing figure in his childhood.
