When Gelsomina, a naïve young woman, is purchased from her impoverished mother by brutish circus strongman Zampanò to be his wife and partner, she loyally endures her husband’s coldness and abuse as they travel the Italian countryside performing together. Soon Zampanò must deal with his jealousy and conflicted feelings about Gelsomina when she finds a kindred spirit in Il Matto, the carefree circus fool, and contemplates leaving Zampanò.

The script, which was written on a day-to-day basis as the film was being shot, concerns the adventures of a motley crew of swindlers and ne’er-do-wells trying to lay claim to land rich in uranium deposits in Kenya as they wait in a small Italian port to travel aboard an ill-fated tramp steamer en route to Mombasa.
