Sunrise: A Song of Two Humans is a 1927 American silent romantic comedy-drama directed by German director F. W. Murnau (in his American film debut) and starring George O’Brien, Janet Gaynor, and Margaret Livingston.
A vacationing Woman from the City (Margaret Livingston) lingers in a lakeside town for weeks.

The Man is torn, but finally departs, leaving his wife with the memories of better times when they were deeply in love.

When she suggests that he solve the problem of his wife by drowning her, he throttles her violently, but even that dissolves in a passionate embrace. The Woman gathers bundles of reeds so that when the boat is overturned, the Man can stay afloat.
The Wife suspects nothing when her husband suggests going on an outing, but when they set off across the lake, she soon grows suspicious. He prepares to throw her overboard, but when she pleads for his mercy, he realizes he cannot do it. He rows frantically for shore, and when the boat reaches land, the Wife flees…
