Inspired by the eponymous book collection that has sold 115 million copies in 150 countries, the series follows the life of the intellectual mild-mannered famous Geronimo Stilton.

The journalist would rather lead a quiet life, spending his days reading or playing chess but adventure always comes knocking on his door! Even if Geronimo is afraid of everything and is not a fan of sports, he always overcomes his fears and saves the day with the help of his geek nephew Benjamin, his prankster cousin Trap and his fearless sister Thea.
