Ernesto and Elena Vega arrive in Mexico City where Ernesto works on a construction site until he is discovered by a local lucha libre trainer. At a time when luchadores--Mexican wrestlers donning flamboyant masks and capes--were treated as daredevils or rockstars, Ernesto finds fame as El Rey Coyote, rapidly gaining name recognition across Mexico.

Years later, in East Los Angeles Freddy Vega is struggling to save his father's gym while Freddy's own son Julian is searching for professional and romantic fulfillment as a Mexican American gay man refusing to be defined by stereotypes. The once larger-than-life Ernesto Vega is now dying, leading Freddy and Julian to find their own passions and discover what really happened back in Mexico.

Told from alternating perspectives, Ernesto takes you from the ranches of Michoacán to the makeshift colonias and crowded sports arenas of Mexico City. Freddy describes life in the suburban streets of 1980s Los Angeles and the community their family built as Julian descends deep into the culture of hook-up apps, lucha burlesque shows, and the dark underbelly of West Hollywood, The Sons of El Rey is an intimate portrait of a family wading against time and legacy, yet always choosing the fight.
