Dr Gillespie (Lionel Barrymore) has cancer and it is getting worse, he is also putting himself under terrific strain while searching for a treatment for pneumonia. His assistant Dr Kildare (Lew Ayres) concocts a scheme to force Gillespie to take a rest. Meanwhile, he takes on a case of a young woman (Helen Gilbert) who has gone blind even though there appears to be nothing physically wrong with her.
Meanwhile, Kildare's father (Samuel S Hinds) might have something seriously wrong with him...
This is a fine little film, well structured and well made. Various plot lines neatly intertwine. The Gillespie / Kildare double-act works very well.
