Plot:
The story begins when Bruce Wayne, CEO of Wayne Enterprises,  comes out of retirement and promises the people of Metropolis to "clean up the mess" caused by Superman and General Zod during the events of Man of Steel 3 years ago. As a response, Lex Luthor and John Corben, CEOs of rival company LexCorp, start building weapons for a counteroffensive against Superman. Bruce Wayne feels very suspicious about Lex. He goes to Metropolis, telling Luthor that Superman is an excellent specimen, but Luthor says that Superman is an Alien that must be killed, opposed to the peaceful idea that Bruce had. Batman, after a year of being out of retirement due to the return of crime and corruption in Gotham , first makes a deal with A.R.G.U.S. to never let Superman destroy another city to prevent any violence between Superman and LexCorp. A.R.G.U.S. trusts Batman with brass knuckles made from Kryptonian atmosphere, a rock called Kryptonite. Superman makes his entrance when stopping a plane that was hit in the engine by a satellite (later revealed to be from Lex Luthor) from crashing into Metropolis. Meanwhile Vice President of Lexcorp John Corben is caught in the explosion and nearly killed. Lex Luthor gives him a robotic body, supplied by a mysterious helper, and powers Corben's robotic body with a large chunk of Kryptonite. It is unknown where he received the Kryptonite. The body Corben is now in allows him to have the strength of 20 average men. Lex tells Corben of a plan he has to kill Superman.

Luthor arranges a meeting with Superman in Gotham City under the pretense of forming a pact. This results in a battle between John Corben, now named Metallo and Superman, and the latter is overcome when Metallo uses his Kryptonite heart to subdue Superman. Batman intervenes, and defeats Metallo. Batman interrogates  Metallo in the hopes to find and take down Luthor, but Superman, disagreeing with Batman's tactics, tries to intervene. A brief fight breaks out, and most of Batman's weaponry is proved useless and armor destroyed. Batman pull out his Kryptonite Brass knuckles and continues the fight. Batman ends the fight when he calls the Man of Steel "Clark", and Superman retaliates and uses X-Ray vision to discover Batman as Bruce Wayne. Luthor disappears after the heroes (or just Superman) apologize for the attack.

Meanwhile, Lexcorp, Luthor's company, merges with Wayne Enterprises in order to help fund the rebuilding of Metropolis. Wonder Woman, sent from themiscyra, is disguised as a normal woman in Wayne Enterprises named Diana Prince. She is at a party at Wayne manor, celebrating the merge between LexCorp and Wayne Enterprises. She discovers a crown/tiara artifact in Wayne manor, which is supposed to belong to the Amazons. She steals it, but on her way out of the reception, she sees Luthor in the background, acting very suspicious.

The mysterious CEO Luthor is shown in the shadows a lot over the next few months, hiding as a manipulator. Another fight between Superman and Metallo breaks out, but the US military intervenes, and breaks up the fight. Metallo is arrested, and Superman is captured by Lex and the corrupt military unit. Superman is placed in an area, filled with kryptonian atmosphere, and Is strapped to a gurney, modeled after the one in the first Man Of Steel. Lex is also wearing a mech suit similar to Zod's, only painted in his own image. Lex sets powerful traps in his base where Superman is kept.

Lois Lane, looking into the mysterious CEO, later discover that Luthor has secretly been taking a serum composed of liquid kryptonite and Mirakuru, the same steroid that Bane and Deathstroke uses, making him lose whatever rationality he had left. Luthor intends to take over the city after using the US air force to bomb it, and will start by killing Superman. He tells Lois and Jimmy that he plans to kill Superman himself, and his robot Metallo is going to help him. Lex then reveals his powerful and various traps, all of which are more than a match for Superman, and in the air is kryptonian atmosphere. He had also planned to get rid of the Batman, which is why he attempted to form a pact with Superman in the first place: to label the Batman as a public enemy. Lex then attempts to kill the reporter so they don't spread the secret plan that Lex has, but Batman intervenes, and subdues Luthor, who escapes with his supplies. Batman placed an untraceable tracking device on Luthor's suit, and tracks him to the base, takes out the twenty-some gaurds, and frees superman, who is in a coma due to the atmosphere.

During the coma, Superman has nightmarish flashbacks to when he killed General Zod and doomed his race. He comes to, and sees Lois at his side.

Lois Lane informs Superman of Lex's entire plan to undermine Metropolis and Gotham. Superman goes to Gotham once again, and decides with Batman that they must put their differences aside and work together. They head to metropolis to stop Luthor from unleashing his plan to bomb the city using a manipulated US military, joined later by Wonder Woman.

Lex Luthor fights Superman in his mech suit, where Superman is severely weakened by him, but is still able to defeat him. He strips Luthor of his armor, and disappears and returns in the disguise of Clark Kent, so he can record this for the daily planet. Batman fights Metallo, and proves to Clark and Wonder Woman that he does not kill when Wonder Woman insists Batman to kill Metallo, but refuses, and then attempts to shut down Metallo with an EMP batarang. However, Metallo breaks free, and attacks Lois, Jimmy, and several bystanders. Clark gets in the way, and Metallo "kills" Clark Kent, who faked his death. After watching the disgust, Wonder Woman kills Metallo by ripping out his Kryptonite heart. Lex later buys the daily planet for his own personal benefit, but is faced with criminal prosecution and sentanced to life. Clark Kent is presumed dead and Superman disappears. The general populace is angered at Wonder Woman and Batman due to collateral damage.

The final scenes in the movie show Superman in exile after the fight. He goes to Martha Kent for advice.
