A social worker goes on a search for her policeman father who went missing seven years ago in the hills of Hong Kong's Sai Kung peninsula after a hiker finds her father's police badge.

In 2005, a high-profile case of a police officer who disappeared during a forest hike spawned urban legends about the existence of a gateway into another world. In 2016, those legends inspired popular internet novel Missing, which is now being adapted into an eerie supernatural thriller by first-time director and Fresh Wave alum Ronnie Chau. Former pop idol Gillian Chung stars as a social worker who hires a mountain guide to search for her missing father in the mountains. She discovers the mystical gateway from the urban legends, but is her father really waiting for her on the other side?

When her mother disappears while on vacation in Colombia with her new boyfriend, June's search for answers is hindered by international red tape. Stuck thousands of miles away in Los Angeles, June creatively uses all the latest technology at her fingertips to try and find her before it's too late. But as she digs deeper, her digital sleuthing raises more questions than answers... and when June unravels secrets about her mom, she discovers that she never really knew her at all.
