A teaser for the blockbuster D.C. taxicab documentary you may or may not have been waiting is out today, and if the background music is any indication, it’s going to be dramatic.

Director Julie Espinosa posted the teaser to her YouTube channel and wrote that she would be following reform in the D.C. taxicab industry over the next four months, viewing the change through the lens of the D.C. Taxicab Commission, independent cab owners, customers, and tech start-ups like Uber.

“This documentary records an established, historic industry in our nation’s capital as it is forced to change under the pressure of market-driven innovation,” she writes.

The teaser includes D.C. Taxicab Commission chair Ron Linton, “The Taxi Link” radio show co-host Pete Tucker, and D.C. cab commissioner and longtime driver Stanley Tapscott.
