Black Spider confronts Jaqqar Marlo, intending to kill him. Marlo tries to get away, but when he believes he has lost Spider, an unidentified individual drops a boulder on Marlo. Spider praises this individual, saying "all the bosses will be proud."
Barbara Gordon is playing a game on the Goode Goggles, when Dick Grayson tries to sneak up on her, but she catches him. They share a romantic moment, but Barbara's attention is drawn to her computer, which flashes an alert.
Brion Markov and Halo are outside Conner Kent's house when Halo gets hungry, so Brion offers her an apple. Conner, Megan Morse and Artemis Crock introduce them to Forager, who has learned English because Megan telepathically downloaded the language into his brain. Halo is eager to share apples with Forager, while Brion is excited to meet Forager because he's a "real alien." Brion half acknowledges Miss Martian and Superboy's status before Halo reveals knowledge of Forager's planet. Everyone is surprised that Halo knows a lot about New Genesis.
Forager explains that he has been exiled from New Genesis and Brion says he can relate. Megan telepathically asks Conner and Artemis where Forager will stay, but they don't have any ideas, until Megan spots her SUV, which is actually her Bio-Ship. The Bio-Ship morphs into a recreational vehicle.
Jefferson Pierce arrives and has contacted Helga Jace by phone so she can talk to the others. Brion asks Helga if his sister Tara is still alive and Helga believes so. She says, after Tara's Meta-Gene was activated, Baron Bedlam took her away, but she doesn't know where. Helga believes Tara has "geo-force" powers similar to Brion and the Baron.
Dick Grayson arrives and informs the others than Jaqqar Marlo was killed by a meta-human and Black Spider of the League of Shadows was spotted nearby. Dick suspects that, because Marlo was killed after a boulder was dropped on him, it's possible Tara is with the League. Helga says, if it was Tara, someone must be using a control device on her, similar to Plasmus. Brion says they must rescue Tara now, but Dick says it's not conclusive that Tara is the perpetrator—it's possible another person with geo-force power, a telekinetic or someone with super strength did the deed.
Brion demands the location of the League. Dick relents, telling him it's on Infinity Island, but warns him they don't know for sure if Tara is there. Brion insists they go, but Dick says they will not face Ra's al Ghul and the League without more proof or a plan. Brion reluctantly agrees to wait and goes inside the Bio-Ship with Halo and Forager.
The three explore the Bio-Ship and Forager is immediately impressed. Brion calls Helga and tells her he intends to go after Tara, saying the others changed their minds about rescuing her. Halo and Forager both say they want to help. Brion wants to know how they can get to Infinity Island and Halo convinces Sphere to take them there.
The others are inside the house when Oracle contacts Dick with information about Halo: her real name is Gabrielle Daou and she is a Quraci refugee who was working as a servant in the Markovian Royal Palace. They leave to tell Halo but discover that she, Brion and Forager are gone. Conner then notices Sphere is gone, too.
Brion, Halo and Forager arrive in the Super-Cycle and ultimately encounter Sensei, who is meditating. Brion demands to know where his sister is but Sensei says he won't find his sister here.
Nightwing, Miss Martian, Superboy, Tigress and Black Lightning fly to Infinity Island in the Bio-Ship. Miss Martian and Superboy remark that what Brion, Halo and Forager did is similar to what Nightwing did with Wally West and Kaldur'ahm when they disobeyed the Justice League and investigated Cadmus Labs years ago.
Brion demands Sensei tell him where Tara is but Sensei only gives cryptic responses, prompting Brion to attack. Sensei fights back, quickly taking down Brion and Forager and subduing Halo. When Halo tries to use her powers, Sensei snaps her neck. Furious, Brion unleashes more lava while the Super-Cycle opens fire. Sensei dodges their attacks before summoning Ubu and a red-hooded ninja to his aid. They defeat the Super-Cycle and Forager, and then Brion and take everyone prisoner.
In the prison cell, Brion blames himself for what happened to Halo, but Halo generates a violet aura and heals herself. Ra's al Ghul observes this on a monitor, but the feed cuts off.
The heroes rescue the others from the prison cell. Before they can leave the island, Ubu, Sensei and the ninja confront them. Nightwing says they just want to leave, but Sensei says their trespass must be punished and everyone fights. The battle ends when Ra's al Ghul arrives and tells Nightwing they may take the others and leave. Brion says they won't leave without his sister, but Ra's says the Shadows may have Tara, but he is no longer head of the Shadows or a member of the Light, so he doesn't have her. Brion doesn't believe him but Nightwing assures him that Ra's is not a liar.
Tigress asks who is leading the Shadows but Ra's won't say. After the heroes depart, Talia al Ghul appears with an infant and the ninja utters the name "Grayson." Ra's is delighted that the ninja's memories are returning.
On the Bio-Ship, Brion apologizes for what happened. Nightwing informs Brion he isn't happy about the situation and Brion understands, saying he needs Nightwing's help. Halo and Forager say they want to stay together with Brion rather than join the Team. Nightwing says that was the commitment he wanted.
Tigress informs Halo they learned more about her real identity, which spurs Halo's memories about her arrival in Markovia and the harsh treatment she received. She insists her real name will be Violet.
Forager surmises that Megan, Conner and Artemis are trying to decide what to do with him, to which Brion and Halo retort in unison "They do that a lot". This refers to the previous two episodes, in which the group was doing the same to them.
Black Spider: I think you do, Jack. See, I've been waiting out here just for you, for hours. Now, I don't begrudge. In fact, I hope you danced up a storm, had a few drinks, kissed a girl. You deserve all that, Jack, because this is your last night on Earth.
Black Spider: Why do they always run? Do I need better quips?
