A surfer learns to be brave on land by loving someone braver than her. Minato doesn't just save people from fires, he makes Hinako want to save herself from drifting. The film knows that love isn't a reward for being ready; it's the thing that makes you ready, and it spends its entire runtime proving it.

Hinako arrives in a quiet coastal town to start university with one certainty: she belongs on the water. Surfing is where she feels fearless, even though she has given little thought to what comes after college. That changes when a fireworks accident sets her apartment building on fire and a skilled young firefighter, Minato Hinageshi, comes to her rescue. As they spend time together, something clicks. Hinako is drawn to how reliable Minato is and how much of himself he gives to helping others, while he grows curious about surfing and asks her to teach him. What begins as a chance meeting turns into a gentle, devoted romance, and Hinako comes to mean a great deal to Minato. Ride Your Wave is a romantic drama with a touch of fantasy, following a young woman still searching for her own direction in life, with Minato beside her.
