Clara has a rare sensitivity: she can see ghosts, but only those who have unfinished business. Lucas, shocked, finally has someone to talk to.

Clara explains that her sister, BEATRIZ, died in the same subway station three months before Lucas. The police ruled it an accident — she fell onto the tracks. But Clara has always doubted this. Beatriz was terrified of the subway. She would never have gone near the edge.

As Lucas grows closer to Clara, he feels himself fading — the more he helps her, the more he “lets go” of his attachment to the apartment. Clara, in turn, begins to heal from her grief, no longer talking to Lucas out of loneliness but out of friendship and purpose.
