In 2067, ruined crops and dust storms threaten the survival of humanity. NASA engineer and former pilot Joseph Cooper is now a farmer. Living with him is his father-in-law, Donald; his 15-year-old son, Tom; and 10-year-old daughter, Murphy. After a storm, strange dust patterns appear on the floor of Murphy's bedroom. Cooper eventually concludes that the changes in gravity caused the patterns and that they are a binary code for geographic coordinates.
