A Royal Institution event with Sean Carroll and Jennifer Ouellette on what happens if you fall into a black hole, covering the firewall paradox, the information problem and the holographic principle.
Recommended as a high-level but clear explanation of the black hole information paradox and competing theories, by a physicist known for making quantum mechanics approachable.

locality is looking suspect for other reasons too, as it's one of the only ways to avoid 'black hole firewalls' [1] (the other way to avoid firewalls involves giving up conservation of information which would be bad for QM theory).

Also see Black hole Firewalls - with Sean Carroll (speaking at 20:25) and Jennifer Ouellette [VIDEO] which explains the paradox and several different competing theories at a high level.
There's a Royal Institute video featuring Sean Carroll and Jen Ouelette[1] that more fully explains the problem, but as I understand it it comes down to a quantum mechanical principle called monogamy of entanglement---there's only so much entanglement to go around, and if two particles (e.g. the pair of Hawking radiation particles) are fully entangled then they cannot have any amount of entanglement with anything else (e.g. information about the black hole). The result in TFA breaks the entanglement between the Hawking pair, allowing the outgoing particles to encode the black hole's information. [1] [VIDEO]
Sean Carroll is a master of making quantum mechanics approachable to non-physicists. Here are a few of his talks: - Fermilab 2013: [LINK] - The Royal Institution 2014: [VIDEO] - The Royal Institution 2020: [LINK]
