A 5 year old boy named Alex, who usually beams with boundless energy, has lately been struggling to sleep through the night. Alex's parents notice a change in their little one's behaviour – a hint of sadness behind the bright eyes, and a hesitancy in the once cheerful laughter. They sense that something's bothering Alex, but every attempt to understand his feelings is met with silence. Parents want to help but they're met with an emotional barrier they can't quite breach.
