Out for a celebratory dinner with Daniel (Michael Shanks), Vala (Claudia Black) is kidnapped by Trust agents working for Athena, a Goa’uld searching for the code to an Ancient treasure map. Athena hooks Vala up to a memory reading device so she can search her memory for the code, told to Vala when she was the host to a Goa’uld named Que’tesh. SG-1 discovers her whereabouts, but during the rescue attempt the device is hit by an energy blast and affects Vala’s memory. Vala escapes but with complete amnesia. She soon finds herself penniless and unable to pay for lunch at a small diner. The diner’s owner takes pity on her and offers her a job and a roof over her head. As SG-1 searches for her, she becomes accustomed to life as Val, a blue plate waitress. However, when Vala takes out two armed robbers liked a seasoned combat veteran, she is taken into police custody and a missing person’s flier is circulated. And Trust posing as SG-1 retrieve Vala from police custody moments before the real SG-1 arrives. But Vala escapes again, and takes Mitchell (Ben Browder), who had been following her, hostage. While Mitchell tries to convince Vala of her true origins and that she is a member of SG-1, the rest of the team desperately tries to locate them before the Trust resurfaces.
