Lucia's little sister Gemma wants to be a luchadora like her big sister, but she is more bumble and splat than pizzazz and seems to find trouble wherever she goes. When Gemma makes a ginormous hole in Lucia's special silver mask, Lucia is incredulous and exasperated at how her little sister seems to get away with everything. But Lucia's grandmother, Abu, has an idea: a trip to the mercado to get Gemma her very own lucha libre mask.
