Title pretty much sums it up. Woman getting ready for her first date with a guy she doesn't know and the guy's future self arrives through time travel and tries to talk her out of going. She believes what the guy is saying but she keeps asking questions. She finds out they have children and a life and yeah things went kind of bad marriage wise. Then they guy from the future has to go back to the future and he leaves her there.
She thinks about what happened and what she had been told. She now knows the future of this first date. She finishes putting on her make up and is waiting for the "first date" to arrive.
Hope I am making sense. Not exactly my most sober post and time travel is confusing.
