Description: Mia (Jodie Whittaker) has witnessed her neighbor commit suicide. At the bottom of the apartment building where the woman's body lays, Mia discovers pieces of a photograph of an ex-lover. Mia is convinced this is a reflection of her own future, and with the assistance of the building's kindly caretaker (David Warner) - and a residential elevator that encompasses the ability to travel back and forwards through time - is able to revisit the most significant stages of her life, with the hope she can stop the event from happening.
