Plot Overview

Joanna (Rachel Shenton) moves to the quiet town of Flinstead with her son Alfie, hoping for a fresh start.

The cast includes Emily Atack, Joanne Whalley, and Samuel Anderson, delivering a gripping mix of mistrust and twists.

Viewer Reactions

Forum chatter and YouTube reviews call it "soapy" and "silly" for some—perfect background TV with drawn-out plots better suited to 2-3 episodes, though others praise its enthralling fear-of-the-unknown vibe. One reviewer rated early episodes 4/10, noting uncomfortable child killer elements but appreciating the market for Channel 5's style. No word on a series 2 yet, and watchers debated if five felt too long.

"Five episodes... probably better for two or three. Five is far too many." – YouTube reviewer on pacing.

By early 2026, all episodes are available on Channel 5's streaming platform (My5/channel5.com) for catch-up.

TL;DR: 5 episodes total, fully aired in September 2025—check My5 to binge now.
