Parnrat Kritchanchai

Worried about her husband being allergic to dust, Nat, a recently-dead woman, returns as a ghost possessing a vacuum cleaner to clean the house and protect her family from other vengeful ghosts in the house. To become a useful ghost, she needs to get rid of the useless ones.

The story takes place inside a small kitchen in Bangkok. Every year, for some days in May, a brother and sister get together there to cook and reminisce about their deceased father.
