 		<meta id="long-description" property="se:long-description" refines="#description">
 			&lt;p&gt;Three male explorers set out to reach a legendary land where only women live, and find⁠—to their surprise⁠—that the legends are true. This country hidden in the mountains is a feminist utopia. There are no men, nor is there war, poverty, or crime. The residents subsist on food from cultivated forests, maintain immaculate houses and roads, and reproduce asexually through parthenogenesis. Although the main characters are men, their role is to show us how their notions about society and womanhood are humorously upturned.&lt;/p&gt;
