On a remote island off the Cornish coast, a volunteer environmentalist records daily observations about a rare flower growing near the cliff edge. Going about her tasks with meticulous care, the nameless ecologist lives a life of isolation and repetition, her routine only occasionally interrupted by a local man who comes to deliver petrol for her antique power generator. But as changes suddenly appear on the plant she is studying, the boundaries between reality and fantasy begin to blur, plunging the volunteer into a nightmarish, metaphysical dreamscape.

Triumphantly delivering on the promise of his extraordinary debut, Jenkin’s sophomore feature is a fascinatingly abstract, almost dialogue-free throwback to the British folk horror films of the 1970s – steeped in cine-literacy yet bracingly singular in its own right.
