Alan is being cared for by a French family close to a German airfield. Gradually recovering from his accident, with the help of the daughter of the house, Françoise, he conceives a plan of escape. Just as C Flight are being congratulated by the general on the success of their "forward action", a German attack on Sainte Marie takes them by surprise. All but one of the planes are destroyed, and several men are killed. Bravington, frustrated at no longer being able to take an active part in missions, quarrels with Triggers over how to retaliate; Triggers forces the remaining men to work all night to repair the one surviving BE2. Disguised as a peasant bringing the early morning milk delivery, Alan gains entry to the German airfield and manages to make his escape in an Eindecker. However, lying in wait for him is Captain Triggers in the last BE2, intent on taking his revenge for the attack on Sainte Marie. Having forced down the German plane, he is about to shoot Alan when they recognise one another. Back in England, Molly has become resentful of the amount of time Lorna is spending with Charles, and she quarrels with both of them over their apparent betrayal of Alan; Lorna herself is convinced that Alan is dead. Charles takes Lorna to meet his family, but only his sister Kate is at home. When they are left alone, Kate forces Charles to admit that he is in love with Lorna. Triggers sends Alan home on leave, in the expectation that his wedding to Lorna will take place. However, the news of Alan's safe return causes Charles and Lorna to acknowledge their feelings for one another, and Lorna tells Charles she cannot marry Alan. (thetvdb.com)
