Bad Biology is a subversively chaotic body-horror comedy directed by Frank Henenlotter and co-written by rapper R.A. the Rugged Man. The film explores themes of sexual mutation, loneliness, and biological curses taken to fluid-drenched extremes.

The story follows two characters burdened—or blessed—by extreme biological mutations. Jennifer (played by Charlee Danielson) is a photographer born with seven clitorises and a hyper-accelerated reproductive system that causes her to give birth to "freak babies" just hours after conception. Across town, Batz (Anthony Sneed) struggles with a massive, steroid-injected penis that eventually develops its own consciousness and detaches from his body to go on a rampage.
