One Valentine's Day night, a young couple was found dead in a lover's alley. After investigation, it was embarrassing that they had got their own families, which surprised their families. 13 years later, Sheriff Tom (Matt Riedy), the husband of the female victim, has been quarrelling with his daughter Mandy (Jori Wanquist) over the death of his wife, while Penny (Suzanne Bouchard), the spouse of the male victim, has been trying to hide the death of his father from his son Michael, who still hovers over the heads of the two families. To make matters worse, the murderer successfully escaped from prison, and another year of Valentine's Day is coming!
