If you've seen the preview for this movie, you know the whole story. Richard Gere brings home a lost puppy he finds at the train station. He grows attached, and his wife reluctantly agrees that they can keep him. The dog follows him to the station every day, then comes back to the station at the end of the day to greet him as he gets off the commuter train. Gere dies, but the dog still greets the train every day. He does so for years, and becomes a fixtures in the little town.
Bottom line, 3 stars.
