Dawson (James Marsden) and Amanda (Michelle Monaghan) were once a couple who had been dating for many years and had a very good relationship. However, opposition from the family and changes in life gradually made Amanda move away from Dawson, and Dawson accidentally killed someone in an accident and went to jail. Upon learning the news that Dawson was imprisoned, the kind-hearted Amanda went to visit him, but Dawson, who thought he was not worthy of Amanda, avoided him. Over time, Amanda had to give up. Twenty-one years later, Dawson became a driller after he was released from prison, and Amanda also found a man of her dreams and married a woman, but Amanda still missed Dawson in her heart. The death of an old friend brought Dawson and Amanda back together, and they needed to deal with the funeral of the deceased together.
