"The Dead Line" aired as BBC Radio 4's Afternoon Play on 3 July 2009 and features the series' regular cast.

Upon seeing the body and meeting Ianto, Stella comes to the conclusion that Jack is more entranced than comatose; as his monitor is still relaying faint signs of activity.

Jack notes the vintage appearance of the phone while Gwen's scans reveal that there are faint signs of residual Rift energy.

Whilst eating breakfast, Gwen notes that everybody with a mobile phone is in danger and is effectively carrying a bomb.

Stella suggests that there is nothing physically wrong with Jack to cause his condition, that an electrochemical reaction to what came down the phone line is what has entranced him and the others.

After breaking in, Gwen and Rhys discover masses of copper wiring and a dead body holding a phone.

They head to Swansea, where the Cardiff and West Building Society now stands in order to find out more about Maddock House.

He goes onto admitting that he knows there will be a day when Jack would not come back to him but they would not have to worry about that problem as long as they work for Torchwood as no member lives to old age.

In Swansea, Gwen and Rhys meet with Mr Tyler, who runs the Cardiff and West Building Society.

He feigns ignorance about the telephone and after being pressured, asks Gwen and Rhys to follow him to a nursing home the company owns.

Maddock House had been hit by a thunderstorm in the seventies which caused the phones to ring; and upon answering, people collapsed.

When Gwen and Rhys return to the hospital, more cases of people collapsing are occurring, and after regrouping with Ianto and Stella; they devise a way to combat the problem.
