A tense confrontation after a Romulan scout ship crashed on the storm-wracked Federation world Galorndon Core, bringing Commander Tomalak's warbird across the Neutral Zone to recover its crew.
In The Next Generation episode The Enemy, an away team finds the wreck of a small Romulan craft on Galorndon Core, half a light year inside Federation space. They bring back one badly injured survivor, Patahk, but Geordi La Forge falls into a pit and is left behind when the storms close in.
La Forge is captured by a second Romulan, Centurion Bochra. The planet's electromagnetic fields are slowly destroying both men's nervous systems, and they are forced to co-operate, combining La Forge's visor with a tricorder to find a neutrino beacon sent down by Wesley Crusher.
On the ship, only Worf's blood can save Patahk. Worf, whose parents were killed by Romulans, refuses, and Picard will not order him. Patahk dies as Tomalak's warbird arrives ready to fight. Picard lowers his shields to beam up La Forge and Bochra, and the Romulans are escorted home.
