Mary Grace Concepcion left her husband, Ale, to be a caregiver in Hong Kong. Now, she has travelled even farther, to Canada, in the hopes of one day sponsoring Ale and having children of their own. But when she arrives in Toronto, she must navigate a series of bewildering and careless employers and unruly children. Mary Grace seeks new employment as a Personal Support Worker and begins caring for Liz, an elderly patient suffering from Alzheimer’s disease, whose health is as fragile as her rundown bungalow beside the Rouge River in Scarborough. While Mary Grace’s time with her charge challenges her conservative beliefs, she soon becomes Liz’s biggest ally, and the friendship that grows between them will turn out to be just as legendary as Liz’s past.
