The 12-year-old boy genius Joseph Lucas discovers an experiment in an old diary and a copy of The Invisible Man by H. G. Wells. With the help of a friend (Ali Pantajali) he recreates the experiment and makes a substance to turn people and things invisible by simply spraying it with the trademark green-bottled solution. The effects are reverted, whether intentionally or not, by the appliance of water or by waiting for a couple of minutes. Joe decides not to tell anybody except Ali of his invention.
