Plot summary
In flashforwards to 2049, Nora West-Allen is a forensic scientist working with her best friend and colleague Lia. Together, they discover a mysterious speedster — whom Lia dubs Godspeed — is stealing chemicals from various laboratories. While Nora and Lia investigate a potential target, Godspeed hits Nora with lightning, exposing her own speedster abilities. Initially believing Godspeed was responsible for her powers, Lia finds traces of a power dampening chip, revealing Nora was a speedster since birth and that it was implanted by her mother Iris West-Allen, which soon causes an argument between them. Later, Nora and Lia discover Godspeed's next target is Stagg Industries. Nora tries to fight Godspeed on even footing, but her inexperience with her powers allows Godspeed to steal what he wanted and kill Lia in the process.
After some investigation, Nora learns Godspeed is August Heart, a former intern from Mercury Labs, and that he is stealing chemicals to create an everlasting version of Velocity 9, a drug that was previously used by speedsters Zoom and Trajectory to give them more speed. Nora realizes the only person who can help her is Eobard Thawne, who is incarcerated at Iron Heights. Thawne initially refuses to help Nora, but she eventually manages to convince him; allowing her to defeat Godspeed and avenge Lia. Nora celebrates her first victory with Thawne, who tells her to find S.T.A.R. Labs ' Time Vault to learn her father's true secret. At the vault, she discovers that her father Barry Allen was the Flash and Barry's final message to her before his assumed death.
In the present, Team Flash has been reading Nora's journal. After realizing Lia was murdered, Iris releases Nora from the cell she was imprisoned in by Barry after her partnership with Thawne was exposed, allowing her to tell her side of the story and give her a second chance. Barry however, takes Nora back to 2049 without consulting his team and orders her to never return to the present. He then confronts Thawne, who is awaiting execution for his crimes.
