Hot Dallas Nights(1981)

Nothing is as hot as those Hot Dallas Nights! People in this big, bawdy town get really hot when the sun goes down. And the Brewing family is no exception. Rock Brewing and his wife, Miss Millie, oversee their empire of fertilizer factories from their hilltop estate where anything goes; and when the torrid noontime sun turns into another Hot Dallas Night, everything goes! Especially when R.J. Brewing hatches his scheme to take over another fertilizer business and seduce his brother Robby's wife yet again!
