When a two-day old Hawaiian monk seal named Kauai Pup 2, or KP2, is attacked and abandoned, environmental officials must decide whether to save the new-born animal or allow nature to take its course. Being one of only 1100 remaining Hawaiian monk seals, and facing certain extinction within 50 years, this decision is a particularly difficult one. KP2 is soon rushed on a journey, taking him across the ocean and into the lab of eminent wildlife biologist Dr. Terrie M. Williams, an expert who refuses to give up on KP2 and his species.
