The title may be inspired by a Leonard Cohen song, but this time-travelling melodrama is singularly lacking in inspiration, and often feels like a Mills & Boon reworking of The Terminator. Grieving for her late mother, Jodie Whittaker's nurse returns to her well-appointed London apartment block to see an elderly female neighbour plunge from the roof. Her shock is compounded by the fact that the dead woman was carrying a photograph of Whittaker's former jazz trumpeter boyfriend (Dougray Scott). She finds more surprises among the deceased's belongings before building caretaker David Warner suggests that the answers to all her questions can be found by stepping into a rickety Victorian lift. Considering the limited budget, the sequences set in the past are admirably authentic, and the performances are uniformly spirited. But Alex Kustanovich and Vadim Moldovan's screenplay is riddled with implausibilities that Dana Lustig's laboured direction only accentuates.
