It's Sgt. Matt Boyden's 40th birthday, and to make matters worse, he has to cancel a date to attend an outward-pursuit weekend with PC Vicky Hagen and a group of wayward teenagers. CID investigate the serious bashing of an elderly man, and their prime suspect is Jason Wyatt who had attacked the same man some months previously . Jason is one of the group with Boyden and Hagen, and his aggressive personality causes several arguments and fights over the weekend. Boyden forms a bond with the boy though, and suspects Jason's abusive father had more to do with the attack. Forensics prove him right, but to Boyden's dismay, Jason faces a manslaughter charge as the injuries he inflicted on the man months ago caused the man to die . Hagen promises Boyden a birthday drink, but the relief have organised a surprise party, so they take a raincheck.
