A jewelry robbery occurs in Midtown, and Joe, Eddie, and The Flash are the first to arrive at the scene and catch the suspect. In the evening, a lady came home from work, and the door was locked while driving, when many flying creatures suddenly appeared in the car, and finally, the woman died.

The next day, when the police arrive, Barry suspects allergies, and Barry talks to Joe about Harrison, who warns Barry not to tell anyone about their investigation of Harrison.

"Barry, did you find anything?" Joe looked at Barry and said suspiciously, facing that kind of situation, it was not the problem they thought of at all.

"I think it's a good thing for superpowers to do it, they have this ability, for example, it is possible to manipulate creatures, for example, my speed is completely fine." Barry looked at Joe, and the times were explained, and it was also a situation they didn't expect.

"Barry, we have to be careful to solve it, otherwise we won't be writing the results at all." Joe looked at Barry, serious, he also knew how to solve it.

"I know this, and I hope the situation is also under our control!" Barry nodded and said, it was also understood.

The cutting-edge laboratory studied the case, and it turned out that the woman was stung to death by a bee, but there was no stinger in the car or in the body of the deceased, and the toxins in the deceased's body exceeded the amount of poison in normal bees.

"Simon, you look pretty scared of bees! What's going on? Caitlyn looked at Simon and said lightly, obviously she couldn't imagine that this scientist was so used to it.

"This is a problem I have since I was a child, I have been bitten by bees, so this is what we should solve." Simon said helplessly, quite embarrassed, to let others know such a situation, it was also something they couldn't think of.

At this time, Felistie arrives at the cutting-edge lab, and she invites everyone to see the latest results, which turns out to be Felisti's boyfriend, Ray. He flew in the sky in special clothes. Barry blames Felistie for making a phone call before she arrives, because Barry has been in trouble lately.

Ray calls himself Atom and everyone is happy to be friends with Ray, Barry interrupts everyone by saying that they have something important to do right now, Harrison and Caitlin say they will help Barry, Barry invites Felisty to coffee, and Harrison notices that Barry is different.

"Barry, you've been through a lot of things since you became the Flash." Dr. Wells looked at Barry and said lightly, facing such a situation, it was something they couldn't have imagined.

"That's right, now that you've become a Flash, you can't give up what you're supposed to do." Barry said with certainty that they understood the situation.

Iris finds Add, he thinks Eddie has something to hide from him, Eddie doesn't admit it, and Iris turns away. Eddie tells Joe that he can't hide the Flash's true identity, and Joe warns Eddie no. Felistie and Barry have coffee, Felisti sees that Barry has something on his mind, and then a depressed Eddie finds Barry, and Eddie says that there is a gap between herself and Iris, and she can't continue to endure it.

"Add, what's the matter you don't want to tell me?" Iris looked at Eddie and said seriously, they are also enough to think about solving this world.

"I don't have anything to do, don't think too much about it." Eddie waved his hand and said, for Iris, they can't say this at all, otherwise everything will be something they can't think of.

A man walks into the building, and before he knows it, a woman has used bees to target him. In the cutting-edge laboratory, Sisko suddenly remembered the quarrel he had with Harrison during time travel, and suddenly remembered something. Everyone receives the case of killer bees, and when the Flash arrives, the victim is Ekinsley, at which point all the bees come out of the deceased's mouth and start tailing Barry, and stab Barry, who is in cardiac arrest and temporarily in shock.

"Barry, we're in danger, let's get there!" Caitlyn looked at Simon and said solemnly.

"Hurry up and contact Joe, he's there." Simon said nervously, they were also quite thoughtful about Barry's safety, otherwise they wouldn't be able to find it.

Joe immediately calls Sisko, who uses his clothes to give Barry a heart shock, and Barry regains consciousness. Back at the cutting-edge lab, Barry asks Sisko why he's pointing the wrong way, and everyone sees Barry's restlessness. What everyone didn't know was that the bees had been following Barry to the cutting-edge lab.

In the evening, Felisti, Ray, Iris, Eddie, and Barry eat together at a fancy restaurant. In the evening, Sisko finds Joe, who says that he found information about the second deceased, who, like the first, was working as a robot. Sisko is asking Ah and Joe to talk about Barry, because he senses that Barry is not usual, Joe says that Barry may just be worried about the case or reverse lightning, Sisko suddenly remembers that Harrison had told him that he is reverse lightning, Sisko panicked and got up to leave.

Simon's memory is also chaotic, and the impact on the past timeline is enough for them to consider, and everything is in the process of attention.

At the dinner table, Iris praises Felisette for sharing everything with Ray, Eddie is embarrassed on the side, Felisti senses that Iris and Eddie are wrong, Ray praises Harrison as his hero, Eddie becomes very upset when he hears Harrison's name, he gets up and leaves, Felicity chases after him, Barry tells Felicity about his suspicions, Felicity doesn't believe it.

"Dr. Wells, it may be reverse lightning, and I don't know what to do." Barry looked at Hitty and said helplessly.

"That's something we can't be sure of at the moment." The other party looked at the Flash and said solemnly, it is also the situation that they continue to understand.

Add and Iris explain their concealment, but Iris refuses to forgive Eddie for his distress and leaves angrily, and Eddie has to follow first. At this time, Barry received information from the cutting-edge laboratory that something was wrong, and Barry immediately rushed back. It turned out to be the bee that was doing it, and Barry caught the bee with great speed.

"Chance, hurry up and find that guy!" Barry looked at his friend and said lightly, these are also things that they didn't think of at all, everything is also in the process of their consideration, so they can solve everything, so these changes are beginning.
