Thomas wrestles with a growing attraction to Kitty, and Joan reveals a dark secret to one of her patients.
While Thomas may not be prevailing with Kitty, he is having success on the wards with a pioneering wound irrigation system.

A terrified patient faces court martial. There's little anyone can do, and yet, his presence unnerves the staff and patients, a constant reminder of the perils of overstepping the rules. This warning is particularly pertinent for some, as a proud Irish non-commissioned officer faces rebellion from his young protégé.
