The ten-year-old twins Julian and Sophie spend their summer holidays by the sea. During a boat trip they encounter a pod of dolphins. Suddenly the animals are startled by something. They speed towards a fishing boat and one of the marine mammals gets entangled in the net. The children manage to free the dolphin but he is injured. After a severe thunderstorm they finally discover him in their bathing cove, which is separated from the open sea by a reef. Julian and Sophie hope to get help from the vet of the Dolphin-Theatre. But is the owner of the dolphinarium really interested in helping the wild dolphin or does he have an ulterior motive?
