A lonely professional single mother plots to get her money back when she is lured into a costly and terror filled situation by a professional psychic who convinces her through an elaborate and ingenious scheme that her life is endangered by the paranormal.

Sounds interesting. It can be portrayed in many genres. Comedy or horror or drama to think of few.

Nice, Richiev. A suggested polish:

After being conned out of her son's college fund 30 days before he is to leave for college, a single mother hatches a scheme to con the con and get the money back.

Added a ticking clock. (That the con was a psychic may be integral to the story, but I'm not sure it needs to be in the logline.)

oops, sorry for the typo's.

"After being duped by a psychic out of her sons college fund, a single mother hatches a scheme to con the con and get the money back."

That's a little better.
