Basically the main character wakes up or something else to find EVERYONE on the planet has "vanished" And he/she finds maybe a survivor or to and try to solve the mystery of what happened to the people.
Movies I have found with that plot -
1. The Quiet Earth
2. The World The Flesh The Devil
3. Night of the comet
4. Vanishing on 7th street.
