 Odilin leaves his sick canary (in colloquial Dutch  kanariepiet , hence the title) at Jeffs. Since Ria considers birds unhygienic, especially in a cage in the kitchen, she cries allergy as soon as Jeff sneezes, but neither knows it s his allergy for cats, as Koen s girlfriend has left her pussy with him in a basket he kept hidden in his room helped by Jo. Impulsive Sam takes the canary out of its cage to keep her awake while working on a paper, but tells nobody, so they think it s lost, which starts a regular comedy of errors. Meanwhile Betty, who was just surprised with a lover, takes various noises and excuses to mean the other students have lovers over too.
