Yekaterinburg. A young, clearly suicidal, man is sitting on the edge of a roof for a full hour. Keeping silent, he ignores rescuers' pleas and arguments. He seems to have made his ultimate decision. But the rescuers don't despair. Working until the very last moment they try to get the poor man talking: the idea being that if you can get a suicidal person to engage and talk to you, you have a much better chance of changing their mind.
