What do three men want Lila to do? Does she agree to do it? Why?

They say that they know Sam gets his hair trimmed every Thursday and that he sees Lila on Saturday night as well. They also know that Sam talks in his sleep and they want Lila to record him, coaxing a confession from him that he killed a man. They offer her money, enough to have the life that she wants. She decides that she has no future with Sam anyway and agrees.
