Sally "Sal-Gal" Miyake can't read, but she learns lots of things. Like bricks are made of clay and Vitamin D comes from the sun. Sal-Gal is happy working in the kitchen at Sunnyside Plaza, the community center she lives in with other adults with developmental disabilities. For Sal-Gal and her friends, Sunnyside is the only real home they've ever known.

Everything changes the day a resident unexpectedly dies in his sleep. Sally and her friends are exposed to death and grief for the first time. After a series of devastating events, local detectives Esther Rivas and Lon Bridges begin asking questions. Are the incidents at Sunnyside accidents? Or is something far more disturbing happening?

The suspicious deaths spur the residents into taking the investigation into their own hands.

Sunnyside Plaza is a human story of empowerment, empathy, hope, and generosity that shines a light on this very special world.
