At the age of sixteen, while on a bombing mission from Ireland to Liverpool during the Second World War, he is caught by the British. He is sent to a Borstal, a reform institution for young offenders, in the south of England. At Borstal, Brendan is forced to live face to face with those he perceived as "the enemy," a confrontation that forces a self-examination that is both traumatic and revealing.

In the emotional vortex, he finally faces up to some difficult truths and finds a way to move on.
