Strangers - John Simm (2018) - Sham Tseng Sewage Treatment Works, Tsuen Wan

The "Kowloon Remand Centre" where the Triad is sent after being caught by the cops wasn't anything of the sort but in fact one of the Drainage Service Department's treatment works. This particular one is in Sham Tseng - located about midway between Tsuen Wan and Tuen Mun - an area famous in the past for its roast goose restaurants. This place is right down on the waterfront.
