Homosexuality was illegal in Hong Kong until 1991, so many of the gay men now in their 60s and 70s came of age in a time when they had to conceal who they were.

Ray Yeung's new film, Suk Suk, is inspired by the real stories he heard from those men. It follows two men who begin a secret relationship in later life, and examines the complicated bonds of desire, duty, family and shame.
