For this fourth entry of the fifteen feature films in the much admired Dr. Kildare series, the regular assemblage of talented M-G-M supporting players enlivens a somewhat rambling plot, with acting honours shared by Lionel Barrymore as young Kildare's overseer, curmudgeonly Dr. Gillespie, and Laraine Day, cast as nurse Mary Lamont who has an eye upon James Kildare (Lew Ayres) as spousal material. James, diagnostic intern at "Blair General Hospital" finds he has a rival for Mary's affections in brain surgeon Gregory Lane (Shepperd Strudwick), whose losing streak of dying surgical subjects brings out the compassionate best from the eponymous hero who, clandestinely with Mary's aid, applies the sticky method of insulin shock (accepted at the time of filming as valid) to a Lane patient in order to correct his condition of dementia, possibly caused by Lane's procedure, while at the same time hoping to save the surgeon's waning reputation. The film was successful upon its release due to audience perception that a graphic depiction of the sanctum within a major hospital is being revealed; it benefits from splendid cinematography of John Seitz, and also the familiar sterling cast of the series including those mentioned as well as Frank Orth, Nat Pendleton and Samuel Hinds as the senior Kildare, in addition to a raft of other performing stalwarts.
