The film follows a couple trapped in a flat at the end of the world. Knowing that the relationship is no longer viable, our protagonist, Fay, is in a dilemma between spending the rest of her life with her partner or risking her life to leave.
Genesis chapters 6–9. The end of a relationship feels like the end of the world where there is no hope and future. The world-engulfing flood is a metaphor for the overwhelming sentiment at the verge of losing and letting go of love. The Noah's Ark symbolises hope, and the realisation of salvation renews a person's world.
