Danger de mort (1947)

A chemist is selling "Sirop Soleil" (= Sunshine Syrup) which he makes in his dispensary.He makes a colossal mistake ,putting cyanide in his medicine.And he has sold five small bottles ,one of them to a man just released from jail.The four other bottles take us to different milieus ,as the desperate chemist tries to save the patients without letting them know what he has done,notably in a circus ,where a dwarf is everyone's punching bag.
