Here's my first one sheet for it, revised log line, and tag line.
HOSTILE HEARTS by Freddy L Robinson
Logline: After a routine heart surgery, a middle-aged Black man unknowingly becomes a billion-dollar target when his surgeon hides stolen espionage secrets inside his new mechanical heart valve.
Tag Line: “One man’s heart holds the key to global chaos.”
NOTE: The more I learn from my doctors, the more information I'll be able to plug into the Scriptmatix tools for story development, characters, et cetera.
