Bullied at school for her dyslexia and troubled by her mother's unexplained disappearance, Kara seeks sanctuary sailing the ocean's waves in her father's boat.

Meanwhile, Felix resents his well-meaning parents for dragging him to live by the coast and misses his old friends back in London.

On their first encounter, Kara and Felix take an immediate dislike to each other.

But when they happen to discover a dolphin calf stranded on the beach they know they must work together to save it against all odds.

Their actions set in motion a dramatic chain of events that no one could have foreseen. And soon they must make an impossible choice. Risk their own lives or face losing everything . . .
