When wildlife film-makers Philippa Forrester and Charlie Hamilton-James adopted an orphaned otter cub as one of the family, they had no idea of the challenges that lay ahead of them. Separated from her mother in a flood, the otter cub, 'Grace', would depend on them for everything - their mission was to raise her not as a pet, but as a wild otter, equipped for survival in the wild, so that she could be released when she reached adulthood. Their highs and lows make for a charming, and at times deeply moving, story for the whole family to enjoy.
