A bad day gets worse when Sarah throws Chuck a surprising relationship curveball as the CIA orders Vivian McArthur Volkoff (recurring guest star Lauren Cohan) assassinated. In order to prove Vivian's innocence, Chuck must put his trust in a dangerous ally: her father, Alexei Volkoff (recurring guest star Timothy Dalton). Meanwhile, Ellie suspects that her mother (recurring guest star Linda Hamilton) is interfering with the search into her father's past. (Warner Bros. UK)
