Is there any situation we know of where the second law of thermodynamics doesn't apply?

The second law of thermodynamics is to some degree not a true law of nature but a probabilistic law. It is possible that the entropy of a system can spontaneously decrease; if you have some particles in a box, it is most probable that you will find them randomly distributed throughout the volume but it is possible, though highly unlikely, that you will sometimes find them all resting quietly in a corner.
