The document describes several shots from a nature documentary about fish living in the sea. The first shot shows the peaceful environment where the fish live with sunlight glaring through the water. Subsequent shots introduce the fish characters, showing eggs vulnerable in the water and young parents playing and feeling optimistic. However, a shot of a lurking shark then increases fear for the characters' safety. The size difference between the shark and other fish raises further concern. When the shark attacks the eggs, the father tries to stop it but is knocked out by the shark's tail fin, leaving the outcome uncertain.
