I think they are going to land on a distant planet in the Delta Quadrant and cause a deadly explosion which envelopes the planet in a nuclear winter, and centuries later Captain Janeway and her crew investigate to see if they can find the original probe. Unfortunately, the species living there kidnap the away party and Janeway has to consider leaving them behind or sacrificing three years to relocate the entire population. After many days of contemplation, she comes up with a compromise and works with one of the planet's scientists to develop a material that could neutralize the radiation in the atmosphere. It get's released by detonating photon torcreepes in the troposphere, and then everyone was happy.
Haha, "Voyager".
