When a series of murders in Cardiff are traced to a medical research centre Jack seeks help from Martha Jones (Freema Agyeman), now a UNIT medical specialist. During the raid on the medical centre Owen Harper is shot and killed.
Jack uses the resurrection gaunlet to bring Owen back for two minutes so they can say goodbye. But the resurrection gauntlet activates and attacks Martha, draining her life force and ageing her rapidly. The undead Owen manages to restore Martha to her original age and – perhaps unsurprisingly – she soon heads back to UNIT.
