Arrow season 7

Five months after being exposed as Green Arrow and into his life sentence, Oliver Queen tries to maintain a low profile in Slabside Maximum Security Prison in hopes of getting a reduced sentence, an effort which is complicated when Danny "Brick" Brickwell tries to coerce Oliver into helping him and by him being stalked by Ricardo Diaz's associates. Meanwhile, Felicity Smoak and William Clayton try to cope with witness protection while John Diggle and A.R.G.U.S. continue hunting the fugitive Diaz. Back in Star City, a new vigilante archer appears on the scene, targeting criminals on their list while also helping the city's poor. After being saved from a group of criminals, Rene Ramirez decides to trust the vigilante, despite not knowing who is under the hood. The rest of Team Arrow do not trust the archer and Dinah Drake is determined to make an arrest. Because the archer's tactics, skills, and appearance parallel Oliver's suited persona, the media dubs the vigilante as the new Green Arrow. After being discovered by Diaz, Felicity leaves witness protection to help capture him.
