The first part of the documentary follows the development of a boy and girl, Jan and Suzanne, from birth to adulthood. At age 5, we see them getting into an open-air pool without swimsuits. They then play on the grass. Full rear and frontal nudity.

At age 10, we see them in 'Garden of Eden' type setting, where they share (presumably) their first kiss. Both are completely naked. Full frontal nudity including close-ups of their genitals.

There's a scene with lots of naked Indonesian children standing in a line in the water with tourists amongst them taking photos and filming.

Shortly after we see a close up on a boy's penis as he is being circumcised, again with accompanying tourists.

A boy (12?) is having [simulated] sex with a chicken and a goat. Frontal nudity. He is shown masturbating after that.

Extensive full-frontal and rear nudity of all three boys (Plamen Nakov, 10, Lachezar Yankov, 11, Kyamil Kyuchukov, 5). When the boys reach a river they undress, splash and play. The 2 eldest paddle and swim in deeper water approaching a bridge. There Aleko's hand becomes trapped in the stonework. The eldest runs off fully naked still to seek help.
