Strangers - John Simm (2018) - Lau Fau Shan, Yuen Long

A body is discovered on the beach. An old guy working on the shoreline of Lau Fau Shan sees it on the shore. The smoggy view over to the opposite coast is looking at Mainland China across the Shenzhen Bay. We've seen this are a couple of times in the past. It was where the seaside shootout in Shatter takes place, and also a bit of Spearhead was filmed here back in the early 80's.
