In a stone-walled cell in Bosnia, Renee Palmer's younger brother, Richard (Chris Martin), is being tortured by Balkan rebel Leko Keglevic (Dennis Mirkovic). When his captors leave him alone for a moment, Richard breaks free and runs from the building. He is able to send a message via global communicator to Renee (Jayne Heitmeyer) who, with Liam Kincaid (Robert Leeshock), hurries to his rescue. They find him in the rubble near Keglevic's stronghold, and manage to whisk him away. As they escape, Ronald Sandoval's henchman, Tate (Richard Zeppieri), appears alongside Keglevic. Richard's so-called escape has been orchestrated.

On the Taelon Mothership, Da'an (Leni Parker) and Zo'or discuss Zo'or's desire for human emotions. Specifically, he is in search of what he terms the joie de vivre that gives humans the strength to overcome even the most deadly challenges-something the Taelons could use in their bid to survive. Unfortunately, Renee's refusal to give much-needed Doors International patents to pharmaceutical pioneer Randy Elston (Mark Burgess) has reduced the Taelons' chances of acquiring this human passion for life.

At the rehabilitation center where he has been admitted, Richard tells Renee he had fallen into Keglevic's hands while he and several colleagues delivered supplies to refugees. He is suffering a breakdown, due to witnessing the execution of his captured friends. Elston meets Renee outside Richard's room and convinces her to cooperate with him, promising to use the resulting technology to cure Richard.

Liam and Renee visit Richard and tell him they have learned his colleagues weren't killed after all. They are waiting in Montenegro as part of a prisoner exchange. Richard refuses to listen, distraught by the memory of watching them die. What's more, they tell him he hadn't been held in a prison but in an abandoned soap factory. They begin to suspect there's more to Richard's capture than meets the eye.

Elston performs what appears to be a successful medical procedure on Richard, who then seems cold and distant when Renee and Liam visit him. Richard tells them he is still haunted by a voice, the only English he heard in the prison. What's more, he claims to have heard it in the operating room prior to Elston's treatment. Suspicious, Liam plays an audio tape recorded during the procedure. Liam immediately recognizes the mysterious voice as Ronald Sandoval (Von Flores), attempting to contact Elston.

Elston visits Zo'or onboard the Mothership, presenting two canisters of what he calls "human essence"-quantities of fear and love crystallized in the form of Taelon energy. Sandoval interjects, telling Zo'or these emotions are key components of the joie de vivre he seeks, and that they'll continue siphoning emotions from Richard until they have them all.

The next day at the rehab center, Richard knocks Elston unconscious and takes Sandoval hostage. He straps Sandoval to a table and begins to torture him with neural amplification. Without compassion, Richard intends to inflict deadly revenge on Sandoval. Renee and Liam arrive and Liam is able to overpower Richard and save Sandoval's life.

Renee visits Da'an and pleads for the Taelons to return her brother's emotions to him. She is successful. A few days later, she visits the rehab center again, relieved to enjoy the company of her loving brother once more.
