At the end of The Intern’s Handbook, John tracks down his nemesis Alice but instead of putting a bullet in her head, he puts a ring on her finger and marries her. Together, they execute a hostile takeover of Human Resources, Inc., the “placement agency” that trains young assassins to infiltrate corporations disguised as interns and knock off high profile targets. As HR’s former top operatives, they are successful until conflicting management styles cause an ugly breakup that locks John out of the bedroom and the boardroom.

But when Alice takes on a new HR target, John is forced to return to the office battlefield in a role he swore he would never play again: the intern. What starts out as a deadly showdown turns into the two of them fighting side by side to save HR, Inc.—and their marriage.
