Ribbons tells the story of a dinner party gone awry; first through the antagonistic actions of the host, and latterly through the intervention of a nuclear bomb, which detonates in the city beyond and necessitates the end of dinner

(as you might expect) and the guests' swift departure downstairs to the host's panic room slash fallout shelter.

 

Our host is revealed to be what's known as a doomsday-prepper - his subterranean bunker is equipped with everything that he and his wife need to survive the nuclear winter.

 

Everything has gone according to his fastidious emergency plans - everything except the number of people now sharing the bunker with him. Perhaps there are ways he can thin the herd? It's for the good of humanity, of course...
