In his experiments for food preservation, Dr. Griffin has just made an incredible discovery. There is a formula, entailing taking a combination of monocane and other chemicals, which can make a human being invisible. The excitement is so big to cloud his judgement. He leaves his boss, Dr. Cranley, Cranley’s beautiful daughter, Flora, and his friend Dr. Arthur Kemp and complete the experiments in solitude and unnoticed. He eventually tests the formula on himself and becomes The Invisible Man. There is a major drawback though, he doesn’t know how to reverse the process.
