Explanation:

We use the conjunction unless to mean 'except if'. The clause which follows unless is a subordinate clause (sc): it needs a main clause (mc) to make a complete sentence. When unless comes before the main clause, we use a comma: Unless [SC]it rains, [MC]we'll go for a picnic by the river tomorrow
