The Tears of the Singers

Captain Kirk and the U.S.S Enterprise join the Klingons to avert disaster in the Taygeta V system – where a time/space warp has swallowed a spaceship without a trace.

Spock suspects a link between the anomaly and the inhabitants of Taygeta, semi-aquatic creatures killed for the jewel-like tears secreted at the moment of death.
