Yucatán – Impermanence is a feature-length documentary directed by Dr. Louis Lam that examines the ever-changing nature of culture, history, and human experience in the Yucatán Peninsula of Mexico. The film links ancient Mayan heritage with contemporary life, exploring themes of transience, cultural memory, and transformation — encapsulated in its central idea that nothing remains fixed and everything evolves over time. 

It travels across the region — from Quintana Roo’s eastern coast through Yucatán to Campeche — weaving together: visits to ancient archaeological sites such as Uxmal to understand Mayan cosmology and legacy, engagement with modern Mayan individuals — including a fisherman, traditional dancers, honey growers and shamans, and an ancestral bone cleaner — to show how heritage, identity, and everyday life intersect today, a culinary journey through traditional Mayan food and its influence on wider Mexican cuisine, adding sensory depth to the narrative, and explorations of identity and hybridity, including reflections from someone of both Mayan and Spanish descent. 

The film also includes an underwater dive to explore submerged archaeological and mythic aspects of Mayan history, and frames its arc with ancient ritual scenes that speak to cultural continuity and change.
