A man proposes to a woman from a lower social class! What is he playing at?

In nineteenth-century England, Mary, the daughter of a reverend, is left all alone after his death, with no one to depend on.

Mary is put off by his flippant attitude, but Ian can’t stop thinking about this woman from a lower class and asks for her hand in marriage!
