The purser finds a pair of trousers with the name tag 'Manuel Sanchez' on and knows there is a stowaway on board. Dick finds him hiding in his wardrobe. He tells him he came to England for work but missed his girl-friend in Tenerife. Then Duncan finds him and gets a different story. The two doctors finally work together and, at Tenerife, dress Manuel as a souvenir vendor, knowing the purser will throw him off the ship as he wants.
