Two soldiers: Britains most celebrated military hero & a broken veteran living in the gutters of London. Their paths last crossed nearly twenty years ago. Now amidst a hostage crisis in the Middle East their lives are about to collide again. & the Strike Back is about to begin. John Porter was involved in a hostage raid in Lebanon in 1989. The raid went disastrously wrong several Regiment men died John spared the life of a Lebanese fighter & blames himself for the deaths. Struggling to come to terms with the past John has hit the bottle & is sleeping rough. Colonel Peregrine Collinson was involved in the same raid. He was awarded a Military Cross & is heralded as a military hero. After the disastrous raid their lives couldnt have been further apart. Until now. A hostage crisis in the Middle East draws the enemies back together for the first time. Who will be the hero this time?
