The Bergmann Protocol

The temporal exploration craft, 'Kolibri', is struck by lightning and is forced to crash land at some point in the past. With the possibility of their prime directive becoming compromised, and with time against them, both the crew of the 'Kolibri' and, and the team sent to recover them, must find a way stop the stricken ship's technology from falling into the wrong hands, or face the prospect of an earth-shattering disaster.
