Trained in the skills of sea power, Pi the fish can fight a shark, sink a squid or batter any random predator that ever threatens his friends and neighbors on the reef. Unfortunately, being the only hero in town can take its toll, especially when a group of sharks declares that the end of the reef is soon at hand.
An improvement on 2006's The Reef, this underwater adventure doesn't hold a candle to big studio animation, but its deeply ridiculous plot is charmingly scruffy.
