The boys strip to their underwear & wash themselves in a lake.

At the Polish police station they are sent to the showers as they "stink". All the boys are briefly seen naked while showering.

The boys stop a wedding parade & won't let it pass without a ransom (must be a local custom). They are given alcohol & drink quite a lot & wake up with a hangover.

The boys smoke at times throughout the movie. They are quite young so this might concern some.
