THE DEVIL IN THE BOX (1977)

Alain Brissot, an executive in a major company, was made redundant following a redundancy plan, but decided to put up a fight by continuing to occupy his office against all odds... He soon went on hunger strike, and, after many ups and downs, ended up taking back the job of his former manager, who had himself been ousted following the failure of a lucrative contract with an African country.
