In 1964 a missionary family from Belfast found themselves caught up in a bloody rebellion in the Central African Republic of Congo. Held under house arrest for four months, the McAllisters narrowly escaped death, but 19 of their friends and colleagues were not so fortunate. Now, 50 years on, 89-year-old Bob McAllister is making the 6,000-mile journey back into the heart of the Congo to remember those who died. This film follows Bob on that journey, and tells the story of how the McAllisters came to be in Congo, their arrest and sensational rescue.
