When an irresponsible party girl’s father is framed by the mob, leaving her with an estranged 11-year-old to raise, she must fool social services to keep the child and outwit the mob to get her father out of prison.

"When an irresponsible party girl's father is framed by the mob, leaving her with an estranged 11-year-old to raise, she must fool social services to keep the child and outwit the mob to get her father out of prison."

An interesting premise but it has a few problems. First is the problem of credibility. In order to be able to grow in power and keep that power, the mob has have some pretty smart people. It strains disbelief that a young girl could just outwit them, especially without any resources or experience.
The second problem is that the logline presents two goals. The goal to outwit the mob and the goal to fool social services. The one that sounds more interesting the mob one, so use that logline space to flesh out that storyline more.
What kind of tone is this story? Each goal, to me, brings up two completely tonally different scenarios. The social services one I imagine a comedy type situation where the child have to use antics to keep the social worker from figuring them out. But the mob story I see a legal and crime drama.
I recommend that comedy would make it easier to suspend disbelief in both cases.

Here's my example:?When her father is framed for murder by the mob, a reckless teenager must find evidence of his innocence. (19)
