Maria (Cheng), the matriarch of a Chinese-Canadian family, reveres her workaholic husband Bing for the sacrifices he has made for their family, and worries about her similarly overworked daughter (Oh, in a brilliant performance).
When Maria begins to suspect that Bing is having an affair, she is forced to confront the harsh reality that her world may not be what it seemed. Wrestling with what to do, Maria embarks on a journey of self-discovery and befriends a group of local eccentrics and a grumpy neighbour (McKellar), who make her realize that everyone’s lives are more complicated than she has been led to believe.
