The film, which is loosely based on Sinclair's book, is a study of frontier capitalism at its rawest. It is set in the badlands of the West—all scrub and rocks—where the people are too poor to buy bread and the only solace lies in the wonder-working power of Pentecostalism. The discovery of oil suddenly pours wealth into the community, but also brings all the usual sins of greed and envy. The local preacher is consumed by the dream of building a huge church.
A great movie that I highly recommend. It shows the darkest side of capitalism which in search for money destroys everything of value. Also the darkest side of religion that is all about greed and misleading people. Now we know that in religion There Will Be Money!
