"Pebble" is a study in missed connections, conflicting impulses and thwarted desires, and a prismatic exploration of loneliness and what it means to be an outsider - or an artist. Pebble yearns to be touched by another, but spends most of her days with jigsaw puzzles and a deck of cards. She flirts recklessly with the Medical Orderly and harbors distrust of Nurse Megan, who chirpily promises special treatments via loudspeaker bulletins until one day, a mysterious visitor comes to see her. In his presence, things begin to unravel, and buried emotions are given release through song, dance, and pills shared like snacks. Alternately hilarious and heartbreaking.
