John Drean (Antony Starr) is a park ranger whose marriage to his wife Ana (Sally Stockwell) begins to suffer when their daughter, Pearl (Georgia Rose), goes missing under his care. Four years later, John is still looking for his little girl and his life seems to be at a standstill, while Ana is in a relationship with John's best friend, and the policeman behind Pearl's disappearance, David (Cohen Holloway). Things begin to change for the better, however, when John's father, George (Peter McCauley), believes he saw Pearl walking past a shop window.
