Frost considers retiring from the Police force and plans to get married, ending the series, however DS George Toolan dies of heart failure following a collision outside the church where the wedding is about to take place. It is noteworthy that an alternate ending was filmed, where Frost is killed instead of George, but David Jason chose the 'happier' ending over this one.
