A man finds his pregnant partner drained of all her blood in the tub. She is moved to the bedroom where she remains confined, unable to do anything but staring and blinking. The father-to-be anxiously moves around the flat until he decides to pour the lost blood from the tub into the couple’s aquarium. Hours, days or weeks pass. Something is moving in the aquarium. It seems to be growing larger every day, but without revealing its full shape.
