Is this a scam?

I think someone may be trying to scam me, so I need some advice.

Someone I met online claims to have traveled to South Africa to collect an inheritance. They claim that their inheritance is only in shares and stocks, and that they cannot sell them online. They must pay a stockbroker upfront, even though they claim that their stocks are worth $800,000. They say that the stockbroker will not help in any way until they come up with $2,000 to pay in advance. They also claim that these stocks can only be sold in South Africa.

Does any of this sound legitimate?

Thank you in advance for your time and advice!
