His temporary replacement is New Zealander 'Fanny' Barton whose authority is rejected by most of the pilots. Ordered to intercept an incoming group of aircraft, Barton attacks what he believes is a German bomber and shoots it down, only to later realise it was a British Blenheim. He is sent away to face a court of enquiry whilst Squadron Leader Rex, an upper-crust and calmly confident pilot, arrives to take command.
