The team unlock over three decades of secrets and lies on the Rock of Gibraltar and find the link which solves the cuddle of a playboy shipping heir from '98 and a young local boy from '82. With both cases solved, they return to England where Lane faces a disciplinary hearing, dragging up a passing in custody from his past which threatens his career in UCOS.
New Tricks follows the work of the Metropolitan Police Service's Unsolved Crime and Open Case Squad (UCOS). Led by Detective Superintendent Sandra Pullman, it is made up of retired police officers who have been recruited to reinvestigate unsolved crimes.
The series title is taken from the popular expression "You can't teach an old dog new tricks". The "old dogs" are successful in adapting their skills and experience to modern policing, with their knowledge of past cases proving especially useful.
