A sentient cave that has witnessed the span of human civilization draws seven strangers from different eras and walks of life into its winding passages, each harbouring unspoken desires and shadowy pasts that compelled them toward this mysterious destination. The cave itself, possessed of a sardonic intelligence and ancient perspective, serves as both guide and mirror to its visitors—a knight, a scientist, a hillbilly, an adventurer, and twins among them—as they navigate deeper into realms that physically manifest their innermost ambitions: grand castles, scientific sanctuaries, and other locales born from personal yearning. What begins as individual quests for self-discovery transforms into a collective journey where the cave progressively exposes the genuine nature of each character's motivations and the truths they've been running from or toward.
