Title: Medicine Man
An eccentric scientist working for a large drug company is working on a research project in the Amazon jungle. He sends for a research assistant and a gas chromatograph because he's close to a cure for cancer. When the assistant turns out to be a "mere woman", he rejects her help. Meanwhile, the bulldozers get closer to the area in which they are conducting research, and they eventually learn to work together, and begin to fall in love.
