Geordi works with a holographic engineer to escape an ancient trap.
The Enterprise is trapped by an ancient alien weapon, a trap left behind by a long-dead civilization, which drains the ship's power. Geordi La Forge is tasked with finding a way out, and he turns to the holodeck to recreate Dr. Leah Brahms, the designer of the Enterprise engines, to help him with her expertise.
Geordi finds himself drawn to the hologram, which is awkward when the real Dr. Brahms appears in a later season. The story balances a tense technical problem with a gentle character study of loneliness. The solution is a creative use of the ship's own mechanisms, and the episode is a great chance to see Geordi at his most inventive, as well as his most vulnerable.
