On the Hawaiian island of Kauai, people in need of medical care for their pets often turn to Dr. Scott Sims. The owner of Pegasus Veterinary Clinic, located in his Kilauea home, Dr. Sims and assistants Dia and Ella keep busy treating a wide variety of domestic and wild animals. He makes "house" calls, too -- on beaches and mountainsides, in the water and jungle -- traversing wild, rural and oceanic Kauai topography. "Aloha Vet" profiles a man whose phone is rarely silent. With a heart of gold, Dr. Sims works long hours helping animals that walk, crawl, fly and swim.
