Yesterday’s Enterprise (1990)
Another tale of alternate timelines, this TNG classic brings our crew face to face with a much more desperate version of themselves: an Enterprise-C, from a timeline where the Federation is in a losing war with the Klingon Empire. Beloved for the alt-reality premise that allowed for a brief surprise return for Denise Crosby’s Tasha Yar—infamously killed off near the end of TNG’s first season—it’s also a touching tale of sacrifice and honor, as the Enterprise-C crew faces extinction to give the Enterprise-D a chance to fix time.
