Answer

To be "in on it", means to know about a plan that is only known to a select group. I could apply to a crime or a surprise birthday party for example. It doesn't necessarily imply direct involvement, it's more about the knowledge of a secret plan or scheme.

Answer

You are correct. "in on it" means they were involved.
