Silent Film needs naming

I remember watching this class and liking it.

All I remember is that it is old, silent and B/W. There is a couple, I think some of them are having affairs. They go on a small boat over to a fair. I think the woman who the guy is having an affair with tries to get him to kill his wife?

Thanks!
