Dalma Wickham, having been in Athens to learn Greek, arrives at a British Steamer to return to London to find that they will not allow her dog, Twi-Twi, on board. Because she is turned away from the British ship, she walks round the quay and sees a most magnificent yacht. While she is admiring it, a bomb goes off at the end of the quay and the seamen leave the yacht to see what has happened.
