I just saw a bit bizarre movie named "Walker". It was supposed to tell the story of one William Walker who invaded Nicaragua in 1855 with small group of soldiers, took the capital Grenada and appoint himself president in 1856.

The film was made in 1987 and was more than a hint to Ronald Reagan policy in central America. In some scenes you see a Mercedes going by and the 1855 soldiers drink Coca Cola and smoke Marlboro. There is even an Helicopter coming to rescue in a Saigon evacuation style....

You can see the movie's details here.

Walker troops had a flag. a 1:4:1 r-w-r horizontal triband, charged with 7 red stars bordered gold in semicircle around a device (volcano?) and unreadable inscription on the red stripe.

I checked the net, and the story in the film was not following the historical fact and the film-makers took a lot of liberty in their script.

We have a (non-fictional) Walker flag here which have no resemblance to this one.
