Dylan lives on a remote island in the Pacific Northwest with his parents, but when they have to go to the mainland, his grandfather weathers a storm to come spend time with him. Grandpa's brought Dylan a number of gifts, and one comes in handy the next day while they are exploring the coast. In fact, this gift leads the duo to a dangerous discovery: a young orca got stuck on the rocks during the storm. Racing against the sun and the heat, Dylan and Grandpa need to work together to figure out how to save the calf while his pod circles nearby.
