The voice of Evie, who died in a fire a decade ago, unexpectedly emerges, warning Joan not to open the third door. Mara, a sound restorer returning home, is Joan’s former lover.
The audio Mara edited back then framed Joan’s father unjustly. As they investigate, they discover the old recording was tampered with and modified emergency systems caused the disaster.
Letting go of their rift, they uncover the truth and reject online vigilante justice. On Halloween the next year, they stage a play in a new theatre to honour the dead and walk hand in hand toward an unlocked exit.
