It is set in the surgical wing of the fictional Grey Sloan Memorial Hospital, located in Seattle, Washington. The season picks up right where it left off at Owen and Amelia 's wedding. After Alex Karev ( Justin Chambers ) had found a drunk Jo Wilson ( Camilla Luddington ) with Andrew DeLuca ( Giacomo Gianniotti ) in a compromising situation during the previous season 's finale, he beats DeLuca to a pulp, sending him to the hospital and subsequently landing Alex in jail. Alex is charged with a felony and is at risk of serving substantial jail time until DeLuca drops the charges. Later, when Alex questions why Jo had turned down his proposal, she reveals that she is already married and has run away from her abusive husband. Meanwhile, Nathan Riggs ( Martin Henderson ) continues to pursue Meredith Grey ( Ellen Pompeo ) after their recent sexual encounter, though Meredith has trouble letting go of her late husband, Derek Shepherd. Maggie Pierce ( Kelly McCreary ) admits to Meredith that she has a crush on Riggs, unaware of Riggs and Meredith 's blossoming relationship, and asks him out, only to be rejected. Maggie is later faced with a bigger issue when she discovers that her adoptive mother has cancer and has come to Grey - Sloan for treatment ; her mother eventually passes away. April Kepner ( Sarah Drew ) and Jackson Avery ( Jesse Williams ) work together to co-parent their newborn daughter, Harriet, while maintaining a platonic relationship ; however, they sleep together when they travel to Montana to perform a surgery. As Chief of Surgery, Miranda Bailey ( Chandra Wilson ) appoints Meredith as Head of General Surgery and hires Eliza Minnick ( Marika Domińczyk ) to run the training aspect of the hospital. Though Arizona Robbins ( Jessica Capshaw ) goes on to date Minnick, the rest of the staff widely opposes Minnick 's teaching techniques and works to get her fired, only for Meredith to get temporarily suspended in the process. Richard Webber ( James Pickens Jr. ) and Catherine Avery ( Debbie Allen ) argue over Minnick 's presence as well, making their marriage more divided than ever. Owen Hunt ( Kevin McKidd ) and Amelia Shepherd ( Caterina Scorsone ) also have martial issues after Amelia reveals that she does n't want to have kids. This causes Amelia to move out and hide out at Stephanie 's apartment. During the season finale, a rapist is admitted to the hospital and attempts to attack Stephanie Edwards ( Jerrika Hinton ) and a young girl. Stephanie starts a fire to escape the attacker, resulting in the entire hospital being destroyed. Owen 's missing sister, Megan, is found and transported to Seattle ; Meredith reveals this to Riggs and encourages him to return to Megan, whom he was engaged to before she was abducted.

Finch May 4, 2017 ( 2017 - 05 - 04 ) 7.09 April and Meredith discover that their patient has an inoperable heart tumor, which the patient already knew about. While the woman has made peace with it and has resorted to having as much good sex as she can before dying, Maggie ca n't let it go that easily. However, she comes to realize that there 's nothing she can do. Inspired to do what 's good for her in the moment, Meredith removes the tumor on the wall and the Post-it from her bedroom and takes Nathan home with her. Eliza and Arizona have sex after a whole day of anticipation. Richard has to second Eliza 's statement that Ben has been playing it safe lately, while Stephanie lets her anger take over when a religious father threatens to sue the hospital for operating on his son 's life - threatening tumor without his and his wife 's permission.

Owen receives news that his sister was found in a basement after a raid in a rebel - led neighborhood. Amelia supports him and calls Teddy to verify Megan 's identity and secure her transfer to Grey Sloan. Back at the hospital, the doctors are thrown for a loop when they discover that their half - naked car accident victims are n't a couple, but instead a woman who drove off the cliff on purpose to avoid getting raped. This discovery comes too late for Stephanie, whom the rapist has captured to secure an easy way out of the hospital. When the hospital lockdown traps Stephanie and a young girl wandering around the hospital with the rapist, the rapist starts a fire to open the doors. Stephanie seizes the opportunity and sets the man on fire, but he drags himself towards gas tanks in a lab. Just as Stephanie goes to drag him away, the tanks explode. 293 24 `` Ring of Fire '' Debbie Allen Stacy McKee May 18, 2017 ( 2017 - 05 - 18 ) 7.92 As the flames rage throughout Grey Sloan, Bailey issues a mass - evacuation while Jackson and Meredith desperately search for Stephanie and Nathan.

Meanwhile, Owen and Amelia continue preparing for their journey, despite finding out about the incident at the hospital, to visit Owen 's MIA sister, Megan. Back at the hospital, Stephanie is forced to go to extremes as she braves the growing flames on her floor, ending up in the staircase. Crawling towards the roof access with Erin in tow, Stephanie comes to the horrifying realization that her key card is missing, which is needed to open the door. Seeing no other option, she wraps Erin in a water - soaked blanket as she prepares to sacrifice herself. But just as the smoke reaches her, she sees that her key card is within sight and fights to retrieve it. As Stephanie and Erin at last enter onto the roof, Erin codes leaving Stephanie hysterical for help. As Stephanie is performing CPR while screaming for assistance, Ben leads a group of firefighters towards Stephanie 's location, finally rescuing her at last. In the aftermath of the blaze, Minnick is fired by Bailey after an inquiry regarding the fire, Erin is alive and in recovery, Stephanie too is recovering from her burns as she tearfully tells Richard she 's quitting, Nathan finds out about Megan from Meredith who encourages him to reunite with his true love, Maggie is told by April that if she wants she could see Jackson, and Owen and Amelia finally arrive at Madigan Army Medical Center as Megan 's helicopter lands and she is pulled away on a gurney towards Owen, as he at long last comes to terms that his sister is truly alive.
