Peter tries calling Eric, but gets no response. The following morning, Peter receives vague text messages from Eric urging him not to come to Hawaii. Although they are at first reluctant, they all decide to take Drake's offer and fly out to Oahu. The seven students are recruited by Drake to work with him at a laboratory in Hawaii. They are visited by the CEO of Nanigen, Vincent "Vin" Drake, along with his CFO, Alyson Bender, and Peter's brother Eric, who is a vice president at Nanigen. He is joined in the biology lab by six other graduate students: Rick Hutter, an ethnobotanist Karen King, an arachnologist Erika Moll, an entomologist and coleopterist Amar Singh, a botanist Jenny Linn, a biochemist studying pheromones and Danny Minot, a doctoral student studying the linguistics of science. In Cambridge, Massachusetts, Harvard graduate student Peter Jansen is collecting venom from a cobra for further experimentation.

Their deaths are reported as a triple-suicide, and Lieutenant Dan Watanabe of the Honolulu Police Department is assigned to investigate the case. Fong and Rodriguez barely have time to react before they are also killed. Fong begins to question Rodriguez about his cuts, but before Rodriguez can explain, the Chinese man's throat is slit by an unseen force. When he arrives, he notices another man, of Chinese descent, waiting in the office. Shortly after leaving the Nanigen headquarters, Rodriguez makes his way to the office of his employer, Willy Fong. As he makes his way through the halls of the building, however, he begins to notice mysterious, ultra-fine cuts appearing on his body. Disguised as a security guard, Rodriguez enters the unattended building and begins searching the grounds for an unknown object. The building is the main headquarters of Nanigen Micro-Technologies, a research company that specializes in discovering new types of medicine.

The narrative begins with a private investigator named Marcos Rodriguez pulling up to a metal building located on the island of Oahu. Micro followed the historical thriller Pirate Latitudes, which was also found on his computer and published posthumously in 2009. Publisher HarperCollins chose science writer Richard Preston to complete the novel from Crichton's remaining notes and research, and it was finally published in 2011. Upon his death in 2008, an untitled, unfinished manuscript was found on his computer, which would become Micro. Micro is a techno-thriller novel by Michael Crichton, the seventeenth under his own name and second to be published after his death, published in 2011.
