Egg suffers from severe hearing impairment and mild intellectual disability. She is sent to a home for the mentally handicapped when she loses the most important person in her life. Walking alone into a strange community, she believes that her father did the same by starting his own journey along the seacoast. Today is the birthday of Ham. He has been waiting for a new change and for his mother to take him away. However, days go by and nothing happens. Locked up in a security room, he is all anxious and depressed until he meets Egg who is trying to escape. In an abandoned house facing the sea, Ham and Egg build an ark, hoping to sail to the time before the world began.
