The volunteer medics continue to treat extraordinary cases of medical need. Featured patients include Maimouna - a 17 year old girl with a facial tumour which the ship operated on 4 years ago, but has now returned. Ignace - a teenage boy with a neurofibroma tumour which covers half his face, and Nanjire and Nadire - twin girls with identical bowed legs. Maimouna's journey to the ship is dramatic as ship doctor Nerida, who operated on Maimouna 4 years ago, travels to Guinea which has only recently been cleared of Ebola to find Maimouna and bring her to the ship for critical surgery. LIghter moments are told in the twin girls Nanjyra and Nadire.
