The plot could start with the babysitter getting strange messages that seem like blackmail threats. These threats could be related to something she did in her past that she thought was forgotten. As the story unfolds, she realizes that the blackmailer is actually someone close to the family she babysits for. She then has to face her past and also protect the family from whatever the blackmailer has planned. All this while dealing with the normal babysitting tasks like feeding the kids, putting them to bed, and making sure they don't get into trouble.
One possible plot could be that the teens find out a secret about the babysitter, like she failed a really important test in the past but lied about it to her parents. They use this to blackmail her into letting them stay up late and eat lots of junk food. For example, they say they'll tell her parents if she doesn't do what they want.
One plot twist could be that the blackmailer is actually a child's long - lost relative. They use the blackmail as a strange way to get close to the family again. For example, they might ask the babysitter to bring the child to a specific place, which turns out to be a family reunion of sorts.
One possible plot twist could be that the person attempting the blackmail is actually being set up by the babysitter. Maybe the babysitter has been planning all along and has evidence to turn the tables on the blackmailer. For example, she could have secretly recorded the blackmailer making threats which would expose their true intentions.
It could be an ex - boyfriend of the babysitter. He might be jealous that she's spending so much time at this new family's house and decides to blackmail her to get her attention or to make her leave the job.
