## Synopsis (in-house rewrite)

A late-autumn fog thickens over Locharmouth. A chill hum of failing power lines.

A military bunker’s winter exercise leaks radioactivity. The ground shudders at midday. Something hungry climbs.

1956 John Ford stock company, leaning on monster movies.

**Mood tags**: dread, slow-burn
