Can Tintin uncover the secret of Calculus' latest invention?

Strange things are happening in the evening at Marlinspike Hall. Windows, glass, mirrors and vases break without any apparent reason. Professor Calculus, somewhat apathetic to the whole series of events, leaves the following day to attend a conference on nuclear physics in Geneva.
Foreign powers get wind of Calculus' work and send one of their agents to investigate. Sensing danger, Tintin, Snowy, Captain Haddock and the detectives Thomson and Thompson go to Professor Calculus' aide - but what exactly will they find in Switzerland?
This full length animated film is based on the classic graphic novel of the same name by Herge.
