In a section of unexplored space, the Enterprise comes across a marker of sorts that will not let it pass. They destroy the marker and move on but soon find themselves in conflict with an unknown alien who accuses them of trespassing and tells them they have only 10 minutes to live. Kirk decides it's time to play a little poker and literally bluff his way out of the situation by telling the alien that the Enterprise has a device on board that will destroy the alien as well as the Enterprise. The bluff works but the alien turns out to be something quite unexpected. Written by
