Chuck learns more about Sarah’s past when they run into her old high school nemesis Heather Chandler. When Heather’s nerdy husband Mark turns out to be a key player in a new mission, the agents must attend Sarah’s high school reunion to prevent the sale of potentially dangerous super-bomber plans. Meanwhile, Big Mike leaves town for a day and Buy More’s new assistant manager Lester decides to implement a new sales policy.
