Luukas Kolibri is the owner of a firm specialized in cleaning houses and apartments after somebody died. Cases are sometimes weird: a woman died in an apartment full of books after a bookshelf fell on her; a man died in a house transformed into a penguin museum, even his urn is in the form of a penguin; parents of a dead teenage girl want Luukas to clean all of her digital traces on the internet... Cases are weird but never turn into a caricature, they are bizarre but possible and there's a fine humor in the whole novel.

Luukas is well known for his accuracy and good work but at the beginning of the novel he is emotionally not very well after the death of his wife Robin. Little by little, through the whole novel, we discover what has happened to her – she died in a car accident while she was arguing on the phone with him. Their relationship was passionate but also turbulent.

He desperately wants to keep memory of her alive so he starts to take things which for some reason remind him of her from houses and apartments of dead people. At the end his apartment is full of stuff and garbage.

Along with Luukas' story we read parts from a diary of a certain René Demeter, now dead - anonymous sperm donor who wants to meet children conceived with his semen.  We will discover that Robin was one of them and that's the reason why she hated all animals.

Luukas is getting worse and worse, he is so depressed and distorted that he sets his apartment on fire, takes Robin's ashes from her urn at the cemetery, goes to a tattoo shop and gets a tattoo made of her ashes near his heart.

Through the novel we follow a man, successful and efficient owner of a firm, who is losing his mind after the death of his wife because he cannot stand the sorrow.
