The hunt for a killer is on, but who's the number one suspect? Is it Sienna; out on a rampage and determined to get answers? Is it Daren, Nancy and Maxine; panicking and trapped in their web of lies? Or is it innocent-looking Nico, who's facing tough questions at the police station? DS Armstrong will stop at nothing to find out the truth.

The second episode this week set on the same day, from a different suspect in the murder case is from Nancy's point of view. Darren and Nancy realise they've accidentally set Maxine up for murder. Meanwhile, Nancy has a physical meltdown in front of her class. Later, she pushes Nico for the truth about Patrick's death.
