A documentary of a ballet odyssey, Dancing Across Borders, screens on Sunday, July 25, at 4 p.m. at the Capawock Theatre on Main street in Vineyard Haven, with filmmaker Anne Bass attending to join discussion after the screening.

On a trip to Angkor Wat in Siem Reap, Cambodia in January 2000, Ms. Bass came across a 16-year-old boy who moved her with his amazing natural charm and grace as a dancer. A longtime devotee of the world of dance, Ms. Bass felt compelled to give this young boy the opportunity to leave his home and follow a dream that he could not yet have fully imagined.

From the serene countryside of Southeast Asia to the halls of New York’s School of American Ballet to the stage of the Pacific Northwest Ballet in Seattle, Dancing Across Borders peeks behind the scenes into the world of dance, and chronicles the intimate and triumphant story of a boy who was discovered, and who only much later discovered all that he had in himself.

Tickets are $15 at the door or on-line at dancetheyard.org, copresenting with the Martha’s Vineyard Film Society.
