We flashback to 2003, and a new member of the Buy More team who has just spent his “break” from work driving down to Stanford to tell his girlfriend he still loves her. But Jill tells Chuck it’s over; she’s dating Bryce Larkin now.
Back in 2008, Chuck gets called in to help set up computers for a conference when who should arrive? Dr. Jill Roberts, the ex-girlfriend turned scientist. Just as she’s about to tell Chuck what he’s wanted to hear for 5 years, Jill’s boss shows up and whisks her away, but not before Chuck flashes on him in connection with bioweapons. Now Team Bartowski has to figure out what’s about to happen and stop a convention full of brilliant scientists from being the next test subjects for a virus. While Chuck plays the suave spy to get information from Jill, Sarah goes undercover as an Australian scientist and Casey tries to keep the plan together.
