How to break into finance after undergrad in unrelated discipline?

Anyone have advice on how someone can break into a finance related career after graduating in an non-finance related major?

I (M24) studied International Relations at a T-10 US program. Have extensive DC think tank/NGO experience but nothing I would consider to be related directly to finance. I also have significant foreign language experience and have spent time living in foreign countries. I have research experience but mostly in qualitative methods.

What options would I have to break into a finance career path at this point in my life? Which specific career paths within the broader realm of finance would best suit someone with an IR/PoliSci background?
