Smile (2005)

“Celebrate the Incredible Strength of Humanity.”

Introduced to a volunteer opportunity with the Doctor's Gift Program, Katie (Mika Boorem) signs up for a trip to China, where she meets Lin (Yi Ding), a girl with whom she shares a birthday. Lin has a facial deformity that discourages her from ever showing her face, but her friendship with Katie helps her start to see life in a new way.
