JP Morgan "Introduction"(?)

Hi everyone, So I have applied for a few internships at JP Morgan with the referral from a family friend. I was told I could hear from a recruiter soon and eventually got an email about a telephone call for an introduction and "to discuss in more detail". This email is extremely vague and I have no idea whether I should look at this as an interview or simply informational with no opportunities to come from it. What should I make of it? What should I say to go further and maybe make something come of it and get passed on from this call to someone higher up where I can get an internship or something?

Let me know! Thank you so much for all of your help. God bless.
