Hollington Drive follows the lives of Theresa (Anna) and her older sister Helen, played by Rachael Stirling.
The sisters appear close and their families enjoy spending time together, but things suddenly change when a child in their town goes missing.
Amelie's character Eva is the daughter of Helen, and heads off to play with her cousin Ben in the nearby park.
But when the children don’t return on time, Theresa goes in search and her suspicions are heightened when she finds the children on the edge of a woodland area and they appear to be fighting.
Immediately her instincts tell her something terrible has happened.
Amelie is best known for being the voice of Peppa Pig after taking over from Harley Bird last year.
Also last year, she starred in Netflix series The Haunting Of Bly Manor as Flora Wingrave.
Amelie also had a role in EastEnders as Daisy, who was fostered by Mariam and Arshad Ahmed.
The character was later adopted by Ashley and Dan. She appeared in the BBC One soap from 2018 to 2019.
But Hollington Drive viewers were quick to realise where they knew her from.
"Omg its Flora from The Haunting Of Bly Manor #HollingtonDrive," tweeted one.
Another said: "New ITV drama….looks good…..watches first 2 minutes….it’s the Peppa Pig voice girl….now can’t hear anything else! #HollingtonDrive #peppapig."
