The series will air on Hallmark’s subscription streaming service, Feeln.
"'The Eleventh' follows a young girl's journey to getting to know her estranged grandmother in order to bring closure to the past and unite her family," reads a press release about the series.
In an exclusive first look at the upcoming series, viewers can see the tension bubbling as the family attempts to work out their issues.
A young girl is instructed to deliver a letter to her grandmother by her late mother. The mother, who appears only through voice-over, alludes to her family having a "troubled past" filled with lies and "complicated" secrets.
"It's time for this family to be happy," the voice says.
"The Eleventh" premieres on May 5 on Feeln.
