The Hidden Code (1920)
Eccentric chemist Eben Lamont has invented a powerful new explosive and intends to give it to the government. Richard Leslie, the CEO of an explosives manufacturing company, tries to purchase the discovery, but Lamont declines. Fearful that Leslie will steal his formula, Lamont uses invisible ink to tattoo part of the recipe on his daughter Grace's shoulder. A spy for a foreign government learns about this, kills Lamont and kidnaps Grace, hypnotizing her to reveal the location of the formula. Leslie saves her just in time, but her problems are far from over.
