在《20 30 40》中，張艾嘉以三個數字探討都市女性愛得精彩的內心矛盾，新作則回歸家庭，藉三位女角的愛情悲歌展現跨世代女性的美麗與哀愁。郎月婷飾演的女兒薇薇已到適婚年齡，在感情和工作之間不能取捨；張艾嘉飾演的母親年屆退休之齡，受著更年期荷爾蒙變化之苦；吳彥姝飾演的九旬姥姥也不好過，孤獨活著幾十年，總是慣性地壓下心中感受。母女情，隔代親，隨著母親/婆婆/二奶的離世，掀起各人心中的漣漪，化解彼此心結。發生在她們身上的故事簡單真實，除了張艾嘉自導自演，還有名導田壯壯粉墨登場，攝影指導李屏賓、美術指導文念中、音樂創作人黃韻玲也繼《心動》後再次合作，給觀眾帶來最深情的溫暖和悸動。

Sylvia Chang writes, directs and stars in this drama about three generations of women and their love. Weiwei is of marital age but her relationship with a pub singer is mired by family disapproval and intrusions from the past. Facing impending retirement, Weiwei’s agitated mother constantly argues with her daughter and takes her husband for granted. Nearing 90, Laolao has been alone for years, silently upholding a marriage on her own. With the passing of Weiwei’s grandmother and the revelation of a yesteryear romance, these three women begin to change as they reassess love and come to better know each other and themselves.
