Suicide Squad is a 2016 American superhero film based on the DC Comics antihero team of the same name. It is the third installment in the DC Extended Universe. The film is written and directed by David Ayer and stars an ensemble cast featuring Will Smith, Jared Leto, Margot Robbie, Joel Kinnaman, Viola Davis, Jai Courtney, Jay Hernandez, Adewale Akinnuoye-Agbaje, Ike Barinholtz, Scott Eastwood and Cara Delevingne. In Suicide Squad, a secret government agency led by Amanda Waller recruits imprisoned supervillains to execute dangerous black ops missions and save the world from a powerful threat, in exchange for leaner sentences.
By February 2009, a Suicide Squad film was in development at Warner Bros. Pictures. Ayer signed on to write and direct in September 2014, and by October, the casting process had begun. Principal photography began on April 13, 2015, in Toronto, Ontario, with additional filming in Chicago, Illinois, and ended in August that year.
In the aftermath of Superman’s death as depicted in Batman v Superman: Dawn of Justice, intelligence operative Amanda Waller assembles Task Force X, a team of dangerous criminals imprisoned at Belle Reve Prison consisting of elite hitman Deadshot, former psychiatrist Harley Quinn, pyrokinetic ex-gangster El Diablo, opportunistic thief Captain Boomerang, genetic mutation Killer Croc, and specialized assassin Slipknot. They are placed under command of Colonel Rick Flag to be used as disposable assets in high-risk missions for the United States government. Each member has a nano bomb implanted in their neck, designed to detonate should any member rebel or try to escape.
One of Waller’s intended recruits is Flag’s girlfriend Dr. June Moone, an archaeologist possessed by a witch-goddess known as the “Enchantress”. Enchantress quickly turns on Waller, deciding to eradicate humankind with a mystical weapon as a punishment for imprisoning her. She besieges Midway City with a horde of monsters, and summons her brother to assist her. Waller then deploys the squad to extract a high-profile mark from Midway, which is reported to be under a terrorist attack.
Ahead of their departure, they are joined by Katana, a warrior who wields a mystical sword and acts as Flag’s bodyguard. Harley’s lover, the Joker, finds out about her predicament and tortures Belle Reve Security Officer Griggs into leading him to the facility where the nano bombs are made. There, he blackmails one of the scientists involved in the program into disabling Harley’s bomb. On approach, the squad’s helicopter is shot down, forcing them to proceed on foot to their target. Boomerang then convinces Slipknot that the bombs are a ruse to keep them in check. Slipknot attempts to escape and is killed via his nano bomb, while the squad is attacked by Enchantress’ minions. They eventually manage to fight their way through to a safe room, where they learn that their mark is Waller herself, who is attempting to cover up her involvement in Enchantress’ siege.
The squad escorts Waller to a rooftop for extraction, but the arriving helicopter has been hijacked by the Joker and his men, who open fire on the squad while Harley climbs aboard. However, the helicopter is shot down by Waller’s men, and Harley jumps out while the Joker seemingly perishes in the explosion, after which Harley rejoins the squad. Alerted to Waller’s whereabouts, Enchantress’ minions arrive and kidnap her. Deadshot finds Waller’s confidential files and learns the truth about Enchantress. Deadshot confronts Flag, who confesses the truth, causing the squad members and Katana to abandon Flag. With Waller compromised, Flag relieves the squad of the mission, but chooses to continue. Realizing they have an opportunity to prove themselves, they soon rejoin him and locate Enchantress at a partially-flooded subway station. Killer Croc and a group of Navy SEALs, led by Lieutenant GQ Edwards, go underwater to plant a bomb underneath her brother. El Diablo embraces his abilities and manages to hold Incubus down long enough for the bomb to detonate underneath, killing them both as well as Edwards.
The remaining squad members battle Enchantress together, but are ultimately defeated. Enchantress offers to fulfill their deepest desires in exchange for their allegiance, and Harley feigns interest in order to get close enough to cut out Enchantress’s heart. Killer Croc then throws explosives into Enchantress’ weapon and Deadshot shoots them, destroying the device. Flag takes Enchantress’s heart and crushes it, finally freeing June from the curse. Waller, still alive, emerges and the squad members are returned to Belle Reve with ten years off their sentences. All but Captain Boomerang are allowed special privileges. The Joker, who survived the explosion, breaks into the prison and reunites with Harley. In a mid-credits scene, Waller meets with Bruce Wayne, who agrees to protect her from the backlash of Enchantress’s rampage in exchange for access to the government’s files on the expanding metahuman community.
