Mary Kills People

It’s been eight months since Mary and Des framed Grady, their drug dealer, for the deaths of their patients. While Des has been serving prison time to protect his partner, Mary’s been managing surprisingly well on her own – she’s found a new supply of pentobarbital in Mexico, her business has continued to thrive thanks to Annie’s ability to source terminal clients in need, and her ex-husband Kevin has moved in and taken on half the parenting duties following a messy break-up with Louise. Though Jess still suspects that her mother is hiding something, Mary has been working diligently to keep her professional and private lives separate. But secrets can only be hidden for so long when Olivia – a mysterious woman with a connection to Mary and Des – comes to them with a deadly request.

During Mary Kills People Season 2, viewers will see Mary become more entangled in her illegal work, risking her family and ER career even as she tries to keep her worlds separate and her daughters safe. But secrets can only be hidden for so long when the mysterious Olivia approaches Mary and Des with a deadly request. Then, the personal and the professional come to a head when Ben returns, knee-deep in a complicated undercover case. Ben's investigation will collide with Mary's criminal descent, forcing Mary to decide whether to come clean once and for all.

When Ben promises Mary that he can get Travis to turn on Olivia – whom he suspects has taken over Grady's drug empire – she decides to trust him despite Des' objection to place their fate in the hands of a cop. But when Mary discovers that Ben has an ulterior motive that would compromise her business, she and Des are forced to put aside their differences and deal with Travis on their own in order to free themselves from Olivia's machinations. Meanwhile, as Jess gets closer to Heather, Naomi feels left out and competes for her best friend's attention by suggesting they throw a wild party at Mary's house.

Travis is gone, Olivia is satisfied and Ben is betrayed. As far as Mary is concerned, she and Des did what they had to do to solve their problem. For Des, the ends don't justify the means, fearing they've crossed a line from which they'll never be able to return. Meanwhile, Ben decides that Mary can't be trusted and puts a spin team on her. When Des is brought back from the brink of despair by Joshua, his gravely ill young patient, Mary tries to evade the cops so she can help, which culminates in a surprising reckoning. Elsewhere, Jess and Naomi are banished to Nicole's house to do penance for their wild party and Nicole realizes that her sister's strained relationship with her daughter has alarming echoes of their own childhood.

After Ben witnesses Mary help a terminal patient die, he finally comes to an understanding and appreciation for what she does and decides to cover for her. After a sobering heart to heart with Nicole, Mary realizes she's been neglecting Jess for far too long and offers to take her out to her favourite restaurant. Despite herself, Jess is happy to be talking honestly with her mother, but just as Mary is about to "come out" to her daughter, a panicked call from Olivia pulls her away – she's been shot by un unknown assailant and is in desperate need of Mary's medical expertise. Tasked with bringing her back from the brink of death, Mary realizes that life is not sustainable with Olivia still in her orbit. Meanwhile, Des asks Nicole to put her name on the title of the "hospice" (death retreat) and pitches her on their plans for the future, while Ben faces a setback in his investigation into Olivia's drug operation.

Mary and Ben have a plan: Mary will approach Olivia and ask for a life-time supply of pento in exchange for saving her life so that they can trap her in a drug bust and take her down once and for all. But, things get complicated when Mary must deal with the fall-out surrounding Betty Lisko's death, and Naomi reveals the truth to Jess about her mother. As Nicole and Des prepare for Brendan's death performance, the personal and professional come to a head when Ben overhears Olivia reveal a damaging truth about Mary who must make a choice that could change her relationship with Ben forever.
