The boy searches the world for his love interest, and he has first-hand experiences with the Holy Inquisition, with the Troubles in Northern Ireland, and with the Arab–Israeli conflict in Israel.

Candido (Christopher Brown) is a naïve young man raised by a Westphalian baron (Gianfranco D'Angelo) in the castle of Thunder-ten-Tronckh.

He is a devoted disciple of his tutor Dr. Pangloss (Jacques Herlin), a philosopher who instructs him with a purely optimistic moral doctrine.

Always in search of Cunegonda, the protagonist and Cacambo travel first in Northern Ireland, devastated by the clashes between Catholics and Protestants, then in a military camp for Israeli female soldiers, during the Arab–Israeli conflict.

Stefano Loparco [it] comments Mondo Candido as "a visionary work without a precise narrative structure - resembling a certain surrealist production by Alejandro Jodorowski - the film is difficult to categorise in a defined genre, nor does it aspire to be".
