Set in the aftermath of the 2008 crash, Nick Cheung’s film follows a loose-cannon psychiatrist through a city deranged by stock-market storms

An immolated teenager flailing in a run down tenement. A doubledecker bus suspended above a calm sea bay. A dishevelled middle-aged couple frolicking down a high street, caught in their own private musical. There’s an irrepressible fountain of dream imagery erupting out of Nick Cheung’s fourth feature, which imagines Hong Kong after the 2008 financial crash as a nightmarish inland empire awash in outrage, anguish and guilt. “Other people’s money!” crows one investor – but the real business here is other people’s dreams.

Loose-cannon psychiatrist Dr Man (Terrance Lau) is under censure from his bosses for investigating his patients’ private lives. Maybe it’s his own uneasy dreams that motivate him to trespass, though a new bizarre case gives him added cause to go the extra mile.
