## Synopsis (in-house rewrite)

Swamp mist clings to the lab’s rusted stills, autumn 1940.  
A chemist in a soiled coat pours violet serum into vials labeled *Heath & Morton Lotion*.  
Bat wings scrape glass as headlines pile on a newsroom desk.  
This is Bela Lugosi doing mad science on a shoestring—perfect for a stormy night with the lights out.

**Mood tags**: 3am-cult
