There are three plot lines. One, the case that the barrister is currently taking. An old case and a story of the barrister's wife's interest in a youth in a detention center. The third is used to tie up the second in an absolutely implausible co-incidence. That's when the series jumped the shark. The second plot line was clearly end up in only failure for the police. And the first was obvious from the minute they showed the CC camera shots. It was clear where the laptop was. So, the last 2 episodes were completely predictable. It goes just a bit above average for the good start.
If it had been shorter at 3 episodes, it would have been a lot tighter.
