Joe Tom Meador was a 29-year-old U.S. Army lieutenant in 1945 when he stole a trove of priceless medieval church art while stationed in Quedlinburg, Germany, just after World War II.

A one-time art teacher from the tiny North Texas town of Whitewright, Meador clearly knew what he was stealing.

And once he mailed his packages back to Whitewright, the treasures — including a 1000-year-old sumptuously illustrated version of the Four Gospels lettered with gold ink and encased with a jewel-encrusted gold and silver binding — became Meador’s private stash, a semi-secret collection that no one in Whitewright seemed to recognize as valuable or acknowledge as stolen property.

Debuting at SXSW, Austin filmmaker Cassie Hay’s first full-length documentary, The Liberators,digs into Meador’s tale and the decades-long search for the treasure and twisted legal battle that ensued between Meador’s heirs and the German authorities.

Hay places Korte and Honan at the center of her film (both wrote books of their own on the Quedlingburg hunt). But she captures interviews with Meador’s niece and nephew, who inherited his estate; a few of Meador’s friends from the gay community and some observational commentary flashy Texas criminal defense attorney Dick DeGuerin,
