Ros Myers was born in 1973. She is introduced in the first episode of the fifth series as an MI6 officer working under Michael Collingwood. In the same episode, Section D learns that Collingwood is plotting a conspiracy to overrule the Prime Minister, and launch measures to combat terrorism, at the cost of several civil liberties. In the second episode, Ros learns that her father, Sir Jocelyn Myers, is funding the conspiracy, and she persuades him out of it, as the rest of the team stop Collingwood. At the end of the episode, Adam Carter (Rupert Penry-Jones) offers her a position in Section D, which she takes. In the fourth episode, she is angered to learn that despite Harry Pearce's (Peter Firth) promise of going easy on her father, he is instead sentenced to 20 years imprisonment.
