Misako loves to chase the sunlight ‘all the way until it sinks’. As darkness slowly but inexorably closes in on him, Nakamori mourns its loss. Misako works for White Light, a company that provides movie audio descriptions for visually-impaired people. During a test screening, she meets Nakamori, a blunt photographer coping with his deteriorating sight. How to watch, how to notice, how to communicate without being too intrusive or too vague? How to convey the meaning, beauty, poetry of life with only words? Radiance offers a diaphanous meditation on finding light through obscurity.
