Wilbur, as the title suggests, is suicidal. It’s not working, though. Every time he attempts to kill himself, someone rescues him, or it doesn’t work, or something. Damn people just keep saving him.
Harpur is Wilbur’s brother. He runs the second hand bookshop their dad used to own until he died.
Alice is a single mother. She works at the hospital, pinching books to sell at the bookshop.
The film is darkly, subtly funny, well written, well acted, and generally well done. You should watch it.
