Off the stunning coast of California live the world s smallest marine mammals, the sea otters. For eight months, we follow the lives of two sea otter pups, both born at the end of summer but growing up in two very different worlds. One pup lives among the yachts off Millionaire Row. The second, on the rugged, wind swept shoreline to the south. Their tenacity, family bonds and intelligence are all they have to overcome the challenges of life.
