It's been three years since the murder of Stella Tomlinson's teenage daughter, Maisy, but the wound is as fresh as if it were yesterday.

Stella wrestles with whether to trust Charles and follow up about Cleo's disappearance; at the same time, she tries to discover who Charles really is by approaching those who knew him best.

Stella dives headfirst into finding out who really killed her daughter, after a video shows a connection between Maisy, Cleo, the McKellers, and Jessie's boyfriend, Kelvin.

Stella is convinced they're finally on the right track, but Charles tells her to stop pushing, as Teddy's life is now at risk. A stunned Stella refuses to give up.
