This painting depicts part of a Tjukurrpa (Dreaming) story for Gracie's grandfather. A Nungorrayi woman came across two children playing without their parents, so she told the children to hide in a hole while she looked for their parents. Nungorrayi (the brown U shape) went looking, and came across a cave. 

From inside the cave came a roaring noise, so she went in to investigate. Inside she found two angry snakes, one was a king brown, the other was a carpet snake. 

She grabbed the brown snake and bit its head off, made a fire and ate it.
