I agree with G, as far as he went with the explaination.

When electrical current flows, any resistance generates
heat. This could be a faulty plug, faulty socket, or loose
socket that's not making good contact. Or it could be dirt
or corrosion. Replacing both the plug and socket will help,
a lot. Use a good quality socket, and wrap the wires around
the screws (back clamped is OK, back stabbed is not).

Your picture shows one blade overheating. And two identical
sockets overheating. This suggests the problem was in the
plug. Now, the plug and two sockets are damaged and all
three of these need replacing.

If this was a cheap receptacle, that is the expected result.
Put in a
spec grade receptacle (it will be in a box, not loose in a
bin) and it
should be OK.
