Caught in the Act presents amateur and professional filmmakers always on the lookout for wildlife in its natural environment. Every now and again, something incredible happens – a lion ‘murders' a hyena, a great white shark gracefully leaps out of the ocean, a baby hippo miraculously escapes the jaws of death – and somehow, someone captures that unbelievable instant on film.

Each episode is a hodgepodge of daring rescues, competitions over food, maternal instincts, dramatic battles and tragic endings.
