The Heart Mountain Relocation Center near Powell was one of several in the country that interned Japanese-Americans during World War II. The camp now sets the scene for a new musical called “Allegiance,” starring George Takei of Star Trek fame. The story follows the Kimura Family in the weeks after they are forced to leave their farm in Salinas, California and move to the internment camp in Wyoming. Wyoming Public Radio’s Rebecca Martinez spoke with producer Lorenzo Thione and composer Jay Kuo, who co-wrote the play , which will open in San Diego in September.
