In the summer of 1969 the lives of a group of altar boys were changed forever when they witnessed the outbreak of sectarian violence on the doorstep of Holy Cross church in Ardoyne, north Belfast. These were boys who grew up together, but went on to take radically different paths as men. Nearly 50 years on, they reunite at Holy Cross to discover how much their lives have been shaped by being born in one of the most troubled parts of Northern Ireland.
