Leo is a brilliant but shy boy who has just moved into his new school. Here, together with friends Nick, J, Spoiler, Mimy, Emily and Siry, the girl he's secretly in love with, he will live new and fun adventures every day. The school of School Hacks is not a school like any other: the Histrionic Headmaster and the strict Miss Elia contribute to making it a decidedly out-of-the-ordinary institution.
