Deadlock (Star Trek: Voyager)

[1] In this television show, part of the Star Trek franchise, a Federation ship is stranded on the opposite side of the Galaxy as Earth in the late 2300s.

In this episode their ship is split into two versions of itself sharing the same power source, while being attacked by a species of organ harvesting aliens known as the Vidiian.

[2] Voyager hits subspace turbulence and suffers from power failures after passing through a plasma drift to avoid Vidiian territory.

The bursts cause shipwide hull ruptures and casualties, including the deaths of Harry Kim and the newborn Naomi Wildman, while Kes disappears through a space-time rift.

This Voyager's proton bursts succeeded in maintaining the reaction, but damaged its doppelganger, of which the crew are aware due to Kes's arrival through the rift.

The two Janeways meet to discuss options, recognizing they cannot evacuate the damaged Voyager without creating a quantum imbalance.

The explosion destroys the ship and the attacking Vidiians, leaving the damaged Voyager free and returning to normal power-reserves.

They decided to focus the story on the two Captain Janeways and their interactions,[3] resulting in what actress Kate Mulgrew described as "the most arduous and possibly the most satisfying work I've ever done, technically".
