After a year-long hiatus brought on by Covid-19, the Amazon Prime streaming series “One Plus One Is Two” is slated to begin shooting again. Its cinematographer, Colin Munson, is a Dorchester resident, and the show is produced by Hop Top Films.

The series follows Marielle Morin, a fictional advocate for special education in the Boston area, and her family members as it leaps around in time from the 1960s to the present-day.

According to series creator and producer Sharisse Zeroonian, “Morin’s husband and daughter are writing a book about her life and her legacy, but with that comes a lot of challenges. When you’re writing someone’s biography, you’ve got to include all the good and all the bad. Because the book is being written by the main character’s family members, when they have to dig into the past and some of the mistakes she may have made as a wife, as a mother, as a friend, and also her triumphs in these areas, it gets messy.

“The main theme of the show is family and parenting, and what it’s like for parents to make mistakes and rebound from them.”

The series also touches on disability rights. Marielle has a learning disability, but, in the words of Zeroonian, that is not her “only defining characteristic. It’s not so much a disability show. The main character is not supposed to be a symbol for oppression. Rather, she’s a person. It doesn’t whitewash the disability element at all, but it really focuses more on who she is outside of it, and that’s what makes it unique.”

“Now, because of Covid, there’s all sorts of changes I had to make to the script,” Zeroonian said. “I had to cut out some kissing scenes and I had to limit the physical contact that actors can make with each other while still preserving the feeling of the scene. That’s been difficult but not impossible.”

Zeroonian began writing “One Plus One Is Two” as a novel at age 16. Finding that she gravitated more toward dialogue than description, she adapted the novel into a stage play, which she self-published in 2014. Although she workshopped the production at several Boston-area high schools, structural concerns, including length and a huge cast list, made it better suited to a series format. After adapting her script to budgeting constraints, she secured preliminary funding and assembled a local cast and crew off social media groups.

The pilot episode, available now on Amazon Prime Video, was shot just before the pandemic began. New episodes should be available soon, according to Zeroonian.
