Irish drama exploring teenage identity. 18-year-old Helen (Annie Townsend) is asked to play a missing girl, Joy, in a police reconstruction tracing her last known movements. Joy had everything that Helen longs for - a loving family, a boyfriend and a bright future - compared with Helen's own troubled and lonely past spent in care institutions. Over time, Helen begins to immerse herself in the role of Joy, ingratiating herself into the lost girl's family, wearing her clothes and even attempting to seduce her boyfriend.
