From the document:
In Okhrana, no one person controls the game; everybody round the table gets the chance to input. Sometimes an individual will play the role of their protagonist, an émigré revolutionary who acts against the Czarist regime. Sometimes they will be asked to play the character of an antagonist, a member of the Okhrana, one of their informers, a spy or an ally in the French police, the Surete Generale.
Each player must create a protagonist for themselves. The protagonist is an individual upon whom a story will focus. That story is told in the form of six scenes, with the story of each protagonist being told, scene by scene, in order.
The game originally was created in 24 hours as a 24-hour RPG contest entry.
