When John Gray wrote Men Are From Mars, Women Are From Venus, he must have based it on a couple like Jacquelin Ch’ng and Sammy Sum. The two stars of Hong Kong horror flick Are You Here had differing opinions about everything from movie scenes to relationship dynamics.

In the movie produced by Patrick Kong and directed by Jil Wong, they play a cash-strapped young couple operating an IT company with two other friends, Kiang (Alan Luk) and Fun (Jumbo Tsang). Just as they are going through some tough times, a wealthy old lady offers them a huge reward to complete an eerie app that her deceased son was working on.
