How rich is rich in Texas? Why, Texan-rich of course-and to be thought rich in Texas you need to be worth at least £ 20-million. Tonight's film is about four such Texan-rich Texans. An oil man whose wife has a passion for million-pound paintings. The boss of the world-famous Dallas department store where the Big Rich of Texas buy their goodies-goodies such as submarines and solid-gold tooth-picks. The richest Texan (he earns £ 75,000 a day) and the most controversial, for he spends this wealth on what many consider to be reactionary causes. The greatest living showman, builder too of the world's biggest sports stadium. A taste of Texas, home of the brashest, most flamboyant, most controversial multi - millionaires anywhere.
