When to Die (home video)

When to Die  was the fifth and final P.R.O.B.E. film produced by BBV Productions, released 15 April 2015 as a tribute to the late Caroline John, featuring Hazel Burrows taking over the role of Liz Shaw. Patricia Haggard also reappears, here portrayed by Georgette Ellison rather than Louise Jameson.

Synopsis
When Liz Shaw returns from a working holiday in Spain a new and deeply disturbing case awaits.

Corporal 7891Alpha has outlived his usefulness or rather the government can no longer afford to fund the medication. And that can mean only one thing... termination!

At first glance a "government authorised execution" is a simple enough task for the Preternatural Research Bureau (PROBE) team.

But as events unfold, and the truth about Corporal 7891Alpha is revealed, the case becomes far more complex.

Only Liz's wealth of experience, courage and determination can save the day — but not before her her moral compass is knocked off course.

Story notes

 * It is BBV's first release since the home video Zygon: When Being You Just Isn't Enough in 2008.
 * The DVD contains outtakes as a bonus feature.
 * The story is available to stream on Amazon Instant Video in the US.
 * Liz Shaw and Patricia Haggard are presented as a couple. This was only implicit in earlier releases.

Myths
