Ep 16. Blood Fever

Ensign Vorik, a Vulcan crew member on the USS Voyager, is undergoing the Pon farr, a biological mating instinct that Vulcans experience every seven years, causing Vorik to experience uncontrollable emotions and desires. Despite his attempts to meditate and control his feelings, Vorik's Pon farr is only growing stronger, leading to a dangerous situation on board the ship.

As Vorik's behavior becomes more erratic and violent, Tuvok, Voyager's chief security officer, must find a way to help Vorik while also protecting the ship and its crew. However, Vorik's Pon farr reaches a critical stage, and he becomes obsessed with Lieutenant B'Elanna Torres, believing that she is his mate.

As Tuvok and Torres attempt to help Vorik through his Pon farr, they are attacked by a group of aliens who believe that Vorik's condition is a disease and attempt to kill him. While fighting off the aliens, Tuvok is injured, forcing Torres to take a more active role in saving Vorik.

As Torres helps Vorik through his Pon farr, she begins to experience intense feelings of desire and must struggle to control them. Meanwhile, the aliens continue to attack Voyager, forcing the crew to come up with a plan to defend themselves.

In the end, Vorik is saved, and the aliens are defeated. However, the experience has a lasting impact on Torres, who must grapple with the intense emotions that she experienced while helping Vorik. As the episode concludes, the crew of Voyager is left to reflect on the challenges of living in space and the dangers that they face every day.
