A single teacher, living alone in his family's house, allows a stranger to share the home with him before it is to be torn down by developers. The stranger has a fascination with statistics, and claims he can predict crimes based on statistical analyses. Intrigued by this talent, the teacher tells a married, female friend (and former lover) that the man seems to have done what he claims. Then the numbers show that there is a slip-up and a murder that was supposed to have occurred, did not. The stranger is adamant that a balance has to be achieved or the whole town will suffer - and he leaves. The teacher and his lady friend set out to search for the statistician, just in time to see an incident on the river that may right the balance after all - an incident that involves the stranger himself.
