Two bureaucrats, Bertrand (A) and then Morvan (B) enter a sixth floor apartment where they find Croker (C) standing centre stage in front of an open window with his back to the audience, clearly on the point of throwing himself out of it. They are there to carry out a pro bono investigation into "the temperament, character and past life of this potential suicide."

A and B continue, in an almost comic fashion, with the desk lamps flickering on and off, and with a didactic analysis from B of the recounts he carries in his folder. In the end, the pair condemn Croker to jump. When A goes to the window to inspect Croker, however, he is surprised by something inexplicable that causes him to remove his handkerchief and bring it timidly to the would-be jumper's face. The ending is left open to various interpretations such as Croker may be crying, smiling, was dead prior to A and B's arrival or else died during the process.
