In the opening scene, Ichabod (Steven Mattila), a cranky, young exterminator, arrives at the Alamo wanting to have a good time with his long-suffering girlfriend Mary to whom he is both physically and verbally abusive.

Cowboy Regan (Davis) arrives after having not been seen for several days and, after reminiscing with his bar friends, tries a last-ditch effort to save the place by contacting his former college roommate who is now a powerful politician in the state capital of Austin.

Cowboy in the meantime commands the Alamo with his presence by telling anecdotes about his life which includes his recently quitting his job and wanting to go into the "movie business" as an actor.

The argument leads to Mary finally breaking up with Ichabod and driving away in his pickup truck with him angrily running after her on foot as a few of the Alamo patrons laugh and cheer him on.

In March 2016, Last Night at the Alamo's official restoration premiered in Austin, TX at the annual South by Southwest (SXSW) film festival.
