A Scottish farm boy, an abandoned girl, and a Gambian hospital patient all find purpose in the rescue and care of a Scottish osprey they name Iris. Scottish ospreys travel thousands of miles as they migrant each year from their breeding grounds in the Scottish highlands to their wintering sites in Africa. Callum, Iona and Jeneba learn about hardship and the value of friendship in their quest to keep Iris safe from hunters and the perils of nature.
