Sam's three extraordinary friends live in his imagination and materialize on the stage of his mind.

The first represents the fun-loving and witty personality Sam wishes he could be around others.

The second represents a more heroic, determined side of Sam, the part of him that wishes he had the courage to be his best and bravest self.

The third represents the more sensitive side of Sam, that part of him that empathizes with others, even as he keeps himself hidden from them.
