Post-invasion Earth – when an alien aircraft crashes into the bay, the local doctor finds his hippocratic oath is stronger (just) than his hatred for the colonising forces, to pull the pilot out of the sea and onto the beach. Against the wishes of the locals he tends to the alien.
A story told many times before, but handled well, and the ending is chilling, when an opportunity presents itself, and a decision has to be made as to just how high a price might be paid to come to terms with the alien.
