Five years after leaving the CIA to open a catering company, Steven and Samantha Bloom are recruited back into the agency by Carlton Shaw. They take on special missions the regular CIA cannot handle. Having made a pact to never discuss their pasts with each other, the Blooms find surprising new things about their spouse in the course of each mission. They are aided by Leo Nash, a top agent who was once Samantha's boyfriend and geeky computer expert Bill Hoyt, who worships Steven. Lizzy is Samantha's sister, a recovering alcoholic who helps run the catering business and is unaware of what the Blooms are really up to. The Blooms are unaware that Shaw has a secret agenda for reactivating them.
