The story deals specifically with illicit drugs. The insects are genetically engineered to eat drugs. A different insect for each drug. The pathology of the insects involve the drug users in their reproductive cycle. Basically the insects are released. Feed on the drugs. Then attack a user of that drug. The insects larva then use the host as food. Literally eating the user from the inside out. Killing the host when they mature and escape the body. The insects are manifestation of prohibition taken to its merciless unrelenting conclusion.

I thought I was being concise until I read your version. I like the sparseness. Part of me has been afraid to be that essential. But, as your version eloquently illustrates, sparseness is the name of the game with log lines. There is one thing I would change. I prefer the phrase “drug using sister” instead of “addict sister”. How does this sound?

When the government release swarms of junkie killing insects a self-righteous policeman struggles to save his drug using sister.

I know it’s pedantic but the distinction that not all drug users are addicts is really important to the story. I might be wrong. You tell me. Thanks for taking the time to reply.
