The crews of the Enterprise and an enemy Klingon vessel find themselves in uncomfortably close quarters during this episode of the 1960s science fiction series. When both the Enterprise and a Klingon warship claim to be responding to a distress call from a disputed planet, Captain Kirk attempts to settle the matter diplomatically, agreeing to beam a number of the Klingons aboard his ship. However, almost immediately after the Klingons are aboard, the Enterprise is hit with turbulence; the resulting damage traps the Klingons and a number of Enterprise crew members together in the same part of the ship. Old hatreds soon rise to the surface, and the tension brings the groups to the brink of a private war -- but the situation soon changes when they realize that a mysterious third party may have had a hand in orchestrating the conflict for purposes of its own.
