Landmyn ebbs and seethes through a winter family holiday by the beach.
Siblings Colette, Johan and Lisa, one returned from a career in London (or Scotland) apparently making coffee, the other an up and coming playwright and director (plainly the autobiographical hinge of the film – you can tell this because the other characters accuse him of being pretentious) and their younger sister, who is rebelling, presumably as she has dyed her hair red. The three of them find themselves at a beach house somewhere in the Cape, paid for by the older sister, who breaks the news that their mother is coming as well. Portent sets in. Who pays for what is where the faultlines lie.
