Two years ago, she left home in the middle of the night to journey to The Beyond, a phantasmagoric land of the dead, which hosts an annual talent show to crown the Greatest Singer Beyond the Beyond - and Chiquis mama, Julieta, is a luchadora with a dream, to become the most renowned singer ever. Determined to dance with his mama during her performance, young Chiqui sets out with his Papa Diego, the hulking luchador, to find The Beyond himself, and help put his family back together.
