What Happens in Mary Goes Round: Full Plot Summary

The whole story of Mary Goes Round (2017) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Mary, Aya Cash, is an addiction counsellor in Toronto who is secretly battling an alcohol addiction. After getting arrested for drinking and driving and facing a sabbatical from work, her boyfriend leaves her.

Unwilling to admit she has a problem, Mary decides to return to her hometown of Niagara as her estranged father has been pressuring her to reconnect with Robyn, her teenage paternal half-sister whom Mary has never met. Immediately upon arriving, she learns that Robyn doesn’t know who she is and that her father lied to her as he is dying of lung cancer and wants Mary there to help take care of Robyn. Walt Jackson, John Ralston, is at the center of this pressure, and his presence looms large as Mary faces the truth of their fractured family.

Mary reluctantly begins to attend Alcoholics Anonymous meetings where she meets Lou, Melanie Nicholls-King, a former drug addict and home care worker who helps Mary to find work and advises her on how to deal with her father. As Mary and Lou become friends, Mary attempts to pass Lou off as an ex-classmate, however Walt is himself a recovering alcoholic and recognizes Lou from meetings.

When Walt begins coughing up blood and has to go to the hospital Robyn finally learns the truth and lashes out at Mary, blaming her for their father’s lies and refusing to go to school.

Robyn disappears one night and Mary receives an anonymous call telling her where to find her. Mary finds her but on their way home they are pulled over by a police officer and Mary is fined for driving on a suspended license. At the police station in an attempt to comfort Robyn, Mary admits that she is an alcoholic for the first time.

While cleaning up their home Mary discovers old letters in which she discovers she is not her father’s biological daughter. She had also previously held a grudge against her father for having an affair and not contacting her after her mother relocated her to Timmins causing their estrangement, however she finds birthday cards indicating he did attempt to contact her for years after she left. Mary talks the situation over with Lou who encourages her not to confront Walt. Walt attends an AA meeting with Mary where he talks about the importance of staying clean and stressing that it is never too late to want to make a change.

Realizing that Walt will not survive to see Robyn graduate high school Mary decides to organize an early graduation party for Robyn and Walt. Walt dies shortly after and Mary attends an AA meeting where she is given a 24 hour sober chip signifying her desire to live a sober life.
