Seven of Nine discovers an ancient subspace relay network that extends to the Alpha Quadrant. They can send the Doctor through to a Federation ship at the other end, the experimental U.S.S. Prometheus, only to discover that Romulans have taken it over.

Stardate: 51652.3 - When Voyager encounters a disabled Hirogen ship with a wounded Hirogen aboard, Captain Janeway beams him aboard for treatment. Soon, the prey being hunted by this particular Hirogen, a member of Species 8472, boards Voyager, damaging it. The only immediate solution is to let the Hirogen assist the crew in tracking its prey. Finding the creature severely wounded, Captain Janeway puts it under her protection, much to the chagrin of Hirogen. Seven of Nine disobeys Janeway's order and transports the Hirogen hunter and the creature to another Hirogen ship.
