[00:00-00:05] A woman repeatedly deletes a voice message addressed to her estranged sibling. She finally records: 'I found the letter. You were telling the truth.'
[00:05-00:10] Before sending, the lights flicker and her phone receives a voice message from that sibling, timestamped five minutes in the future. The message says: 'Do not open the front door.'
[00:10-00:13] Someone knocks three times. She approaches while replaying the warning, breathing quietly.
[00:13-00:15] Through the peephole she sees herself standing outside, holding the missing letter. Cut to black.
