It's been five months since the explosion in Hell Island. Although chase was in trouble, it was hard to hide his sadness. Most people boarded the supply ship of Eye of the Sky safely, but William's mother Samantha died, and Thea was in a coma, relying only on instruments to sustain her life. William lost his mother and Oliver had to take care of his son. He specially invited the nanny Teresa to look after William's diet and daily life. Only in William's mind, Oliver will always be the bad guy who killed his mother.
Even so, Oliver has to shoulder the responsibility of punishing evil and promoting good, and has just foiled a terrorist attack on Star City with missiles. Mister Terrific skillfully deflected the missile by T-ball and exploded on the sea. Alex Faust, the principal offender, was also brought to justice by the Green Arrows and handed over to the Star City Police Department. Dana, who has just been promoted to vice captain, is not in the mood to interrogate Faust, who is used to blackmailing major cities. She's more worried about Quentin. As deputy mayor, Quentin did not come to the police station to check the upcoming graduation ceremony of the police academy, but sat in front of the bar and stared at the three glasses of tequila in front of him. After the explosion of purgatory island, he and Dana met the Black Sea demon laurel while looking for a supply ship eastward. Quentin shot Laurel himself to save Dana. Seeing his daughter fall, his heart rolled in the abyss.
Dana rushed to the bar to comfort Quentin, not wanting the police station to be attacked at this time. The attacker not only saved Faust, but also razed the police station. Dana got the police surveillance before the media arrived, and was surprised to find that the intruder turned out to be laurel. Quentin and Dana, who witnessed laurel's death, couldn't explain it, let alone know how she left Hell Island. Quentin had a hunch that Laurel came back for revenge, for that shot. After seeing clues about the Black Sea demon and its mercenaries in his eyes, Quentin resolutely decided to act with the Green Arrows. On the viaduct at night, Dana Canary's roar forced the Black Sea demon's van to stop. Other members immediately assembled, launched an attack, killed the mercenaries, and demanded that the Black Sea demon laurel be captured alive.
Dana's combat experience was not enough to subdue laurel, but Quentin hesitated, and the Black Sea demon seized the opportunity to escape. On the other hand, Sparta shot and rescued Rene, a wild dog in danger. To everyone's surprise, Spartan bullets were skewed, which had never happened before. The green arrow behind him made a remedy, but Rene was shot in the chest by mercenaries. After a battle, laurel didn't find Faust, but ran away, and Rene was seriously injured. The only gain is the GPS chip in the car. Felicity searched the information in the chip and found a warehouse.
Canary and Sparta quickly arrived at the warehouse and found a drawing from a pile of abandoned equipment. The map shows the detailed structure of the city hall and the best sniper points around it. Considering that the graduation ceremony of the police academy will be held in the city hall, it is obvious that laurel and Faust are planning the next terrorist attack. John knew very well that when hell exploded, his right shoulder was injured by a flying weight, so he couldn't aim. So, this time, in the security work of the city hall, he volunteered to stay in the bunker, and Felicity went to the scene to assist Curtis in scanning explosives. Oliver and others didn't notice John's abnormality and rushed to the city hall to deal with the upcoming emergency. But the whole ceremony was quiet until the end of Mayor Oliver's speech, and nothing happened. Just when everyone thought that laurel had changed his plan, the Black Sea demon and Faust led the mercenaries to appear in the bunker. Sparta sounded the alarm and then fought the mercenaries. Instead of using weapons, he used fists. But after all, two fists are hard to beat four hands. Fortunately, other members of the Green Arrow team returned in time and killed the enemy.
Laurel, a Black Sea demon, met Quentin on his way out. In deja vu, Quentin's trembling fingers were unable to pull the trigger and watched laurel proudly walk by. Faust planted bombs in the whole bunker, but they were not powerful enough to destroy it. If the map in the warehouse is just a cover, then these bombs are probably also a cover-up, in order to cover up the real purpose of the Black Sea demon. After counting all the weapons in the bunker, Curtis found that his prototype T-ball was missing. The prototype T-ball is just a concept product, and it has no lethality. No one can guess the purpose of the Black Sea Demon taking pains to steal it.
When the storm subsides temporarily, the injured Rene will be discharged immediately, and Slade will also look for his son. Oliver's greatest wish at present is that Thea can wake up and untie the knot with her son William. But before he could breathe, another thing happened. Important news was broadcast on TV, and an anonymous person provided a surveillance photo, which can solve the biggest mystery in Star City in recent two years-the true identity of the arrow. Oliver appeared on the screen, wearing a green arrow shirt and taking off his hood. At this point, Oliver only felt that the air solidified instantly, and he didn't know how to get through it.
