The Prodigal Planet is a 1983 American evangelical Christian horror film produced, directed and co-written by Donald W. Thompson.

It is the fourth and final installment in the Thief in the Night series, based on an evangelical interpretation of Bible prophecy and the rise of the Antichrist.

The Antichrist and his world government find their grip on power slowly slipping away as Jesus Christ's return draws near.

One of the lead characters from the previous film, David Michaels (played by William Wellman Jr.), is now part of a growing underground movement of Christian believers trying to stay out of the government's hands and thus escape execution.

David's mission is to take an RV across a nuclear-devastated landscape to Albuquerque, where he will meet with other underground believers to await Jesus Christ's final return.

Connie is later picked up by a senior UNITE officer (dubbed "General Goon" by David in Image of the Beast).
