After his last mission Alex is deemed sloppy by Blunt, and is in need of training. He is sent back to Brecon Beacons, and much to his annoyance put into K-unit once more. Everything is going as well as it can be, until Alex's carefully constructed walls start to crack, and he is left defenceless against the horrors of his last mission. Can K-unit break through the lies Alex is feeding himself before he breaks, or will they be left to pick up the pieces when it all comes pouring out?
