In Taiwan, "song wa si de" are workers who routinely supply gas tanks to street vendors and old residential buildings. The magical Tank Fairy delivers her tanks unlike any other - with sass, stilettos and a healthy helping of glitter. Her arrival upends the life of Jojo, a lonely ten-year-old who dreams of dancing and drag. Outcast by classmates and misunderstood by his stern, single mom, Jojo is inspired to live out loud by his fierce, propane-toting fairy godmother.
