Selectable English subtitles included. There is a lot of English spoken, especially during the long Othello scene, and the English has no subtitles. 

The Encyclopedia of Indian Film says this about Saptapadi:

Set in WW2, the Jesuit Rev. Krishnendu
(U. Kumar) runs a military hospital in Bankura.
A wounded woman soldier, Rina Braun (Sen),
arrives and he recognises his former lover,
triggering a long flashback showing them as
fellow medical students. She is an exotic
Eurasian and the hero wins her while playing
Othello (he was dubbed by Utpal Dutt,
renowned for his stage performance of that
role) to her Desdemona in a college
performance. His orthodox father (Biswas)
forbids their marriage. The hero converts to
Christianity and exiles himself. Rina discovers
that she is the illegitimate daughter of a Hindu
maid and becomes an alcoholic, eventually
joining the army. Back in the present, Rina tries
to kill herself when she regains consciousness
but the lovers are united in the midst of the war
(Tarashankar’s original story ended tragically).
This Kumar/Sen hit (cf. Sagarika, 1956),
including their characteristic low-angle, soft-
focus close-ups and stylised movements,
yielded one of the most popular song
picturisations of the decade, the classic motor
bike scene number Ei path jadi na shesh hoi.
