They Keep Killing Suzie

Plot:

Using the Resurrection Gauntlet that former Torchwood member Suzie Costello originally had, the team are able to bring a number of murder victims back to life. However, these all have a link with the now-deceased Suzie, and the group have no choice but to bring her back. After the process goes wrong, and permanently keeps her alive, Suzie manipulates the naïve Gwen into taking her to see her father.
