For the first time in a decade, Colette, Johan and Lisa reunite for a winter holiday on the South African coast. Each has built a life elsewhere in an attempt to escape the instability of their childhoods and the long shadow of their mother, Annatjie. The atmosphere changes radically when Colette reveals that she has invited their mother. Annatjie arrives like a storm and pulls the family back into old patterns of resentment, survival mechanisms and unfinished history. Over time, her presence causes the distance they have tried to put between themselves and their past to disappear. Each is forced to ask how much of their lives still revolves around her gravity, and whether that hold can ever truly be broken. Landmine is an intimate chamber drama about inherited trauma, duty and the impossible act of giving up and letting go.
