Logline: Can Earth’s loneliest vampire, his zoologist girlfriend, and endangered-species bats prevent the “Master Vampire" from violating Nature twice: developing unstoppable super-COVID-19, then -- destroying the Sun?
No synopsis yet (would be spoilers); but, just noting that the script is unproduced. ("Pre-production" implies "in development" here) Runtime and production country of USA are guesses.
Feel free to inquire! Thanks.
