Quelli dell'intervallo is an Italian situation comedy produced by Disney Channel Italy. The show focuses on kids as they chat and get into unexpected situations while at a window in their school.
After Disney's success with the show, the idea was replicated throughout continental Europe, and eventually Asia, Australia, and the United States. In total, fourteen different shows have spun off from Quelli dell'intervallo.
The show finally ended in 2009 ending the series with Quelli dell'intervallo - In Vacanza. The show ended with the kids finishing school going to High School.
Young Billy Webb likes to swap things with his schoolmates. He meets Alfonso Bonzo, an 'Italian exchange student' who also has a talent for swapping things (thus his self-description: he is an Italian student who exchanges things). Billy makes a series of magical but increasingly risky swaps with Alfonso, leading to unexpected and sometimes sinister consequences as Alfonso's true nature becomes questionable.
