A green sea turtle, Kate, and her unlikely best friend Cecil, an octopus, play everyday in their beautiful ocean-until a sudden encounter with a speedboat changes everything. Cecil, already distrustful of humans, sees the accident as evidence of human carelessness. Kate, however, experiences human kindness as she is nursed back to health in a turtle rescue center. When reunited, Kate shares a powerful lesson with Cecil: while reckless human actions can harm their ocean, there are many dedicated humans working everyday to protect it.
