JR's taking the train to Denver to be with his family after the death of his grandpa. Although he has all the money in the world, he's terrified of flying so prefers to travel by train. He tries to rest on the train when he's disturbed by an argument happening in the train car. He leans forward to see what is going on and decides to intervene. Little did he know his intervention would change the rest of his life.

Amanda is a pediatric nurse who has always dreamt of having babies of her own. She's on the train to Denver to visit friends. She bought the ticket because it was cheap and she didn't want to drive alone. Now there's a fight in her train car and she's quickly regretting the decision, until the man that was punched needs her help.

Now they've gone their separate ways and didn't exchange any information. JR is kicking himself and Amanda can't stop thinking of him. Will fate make their paths cross again?

A HEA that proves love is serendipitous.
