Merry Go Round (2010)

This is the story of two women, two generations apart, who coincidentally return to Hong Kong from San Francisco where they had their first, fleeting encounter on the streets as strangers. Back in Hong Kong they meet again, still a brief encounter, when one buys Chinese herbal drugs from a store owned by the other. Their lives are actually much more connected, through two unrelated men, as the audience will soon find out.
