Yeah, if it's not a high school, the lingere becomes harder to explain. But there is a scene with either a) elementary school kids running around as class gets out b) a bunch of teenagers with serious endocrine disorders running around as class gets out.

Actually, I think it's an elementary school.

The flashbacks don't bear on the plot in any meaningful way. This version is worth watching if only to see representatives of new and traditional Russian social groups (Novyi Russki, wise old Jew, embittered Sovak, etc…) duke it out in a high school gym.
