愛爾蘭山區小鎮麗南周邊的一間小屋，幽暗且充斥著惡臭味，
兩母女在侷促的空間中互相折騰。女兒Maureen（蘇玉華飾演）的自由
多年來被母親Mag（葉德嫻飾演）肆意踐踏，
二人互相厭惡、仇視，卻終於無法擺脫唇齒相依的生活。
直到Maureen 尋找解脫的機會突然出現⋯⋯

The play is a blend of black comedy, melodrama, horror and bleak tragedy. The story is set in the Irish village of Leenane, Connemara in the early 1990s. It takes place entirely in a shabby, poorly-lit kitchen, resulting in a claustrophobic sense of entrapment.

The play centers on the life of Maureen Folan, a 40-year-old spinster who takes care of her selfish and manipulative 70-year-old mother Mag. Maureen's sisters have escaped into marriage and family life, but Maureen, with a history of mental illness, is trapped in a seriously dysfunctional relationship with her mother.

The Folan cottage is visited by Pato Dooley and his younger brother Ray. Pato is a middle-aged construction worker fed up with having to live and work in England, disappointed by the limitations and loneliness of his life. The day-to-day sameness is tedious also for Ray, a non-threatening "bad boy".

The glimmer of a last-chance romance between Maureen and Pato sparks up in the first act, and continues in the second one with a notable monologue of Pato. The plot, full of deceptions, secrets and betrayals interspersed with turnabouts, keeps surprising the audience. Hopes are raised only to be dashed.
