The body of a murdered federal agent is found, and Five-O is contacted by the government agency that sent him to Hawaii, which also sends another agent, Glen Fallon, to Hawaii to assist Five-O. McGarrett and Five-O discover that the murdered man was investigating the possibility of a "sleeper" agent within the March Foundation, a think-tank funded by the U.S. government. The evidence uncovered by McGarrett and Fallon begins to suggest that the Foundation's chief, Dr. Rathman, is the "sleeper" that the murdered agent was looking for.
