Kate Fosterleaves a beautiful lakeside house in Illinois to work in a busy Chicago hospital. Outside of work, she often blames herself for failing to save a car accident victim on Valentine's Day . Before leaving, Kate left a piece of letter paper in the mailbox outside the door, hoping that the next resident of the cabin could contact her to help transfer her mailing address. The letter also explained the dog's paw that could not be wiped off the front door. Yin had already stayed when he moved in. Alex Weller, the new tenant of the lake house, is an architect. The house has a special meaning to Alex. This is the design of his architect father.
When Alex received Kate’s note, he was already a human being. The cabin was covered with dust and overgrown with weeds. In Alex’s eyes, it looked like nobody cared about it. There was no dog paw that Kate said at the front door. Yin, he was completely indifferent to the letterhead left by Kate. It was not until a few days later that a lost dog accidentally stepped on his freshly painted breakwater and left the paw prints mentioned by Kate on the front door of the cottage. The puzzled Alex finally decided to write back to ask Kate why she would know in advance. There will be dog paw prints in front of the hut. In the correspondence, they found that they were two years apart in time and space. Kate was in 2006, and Alex's time was the same month and day in 2004. Under curiosity, the two continued to communicate, unknowingly moved by each other's experience, until they fell in love with each other, but they did not know that waiting for the two of them would be a car accident on Valentine's Day.
