During the events of Hot Fuzz (2007) played by Julia Deakin
Nicholas Angel walks into the pub and passes by PC Danny Butterman who is ordering a drink from Mary. He orders a cranberry juice from Roy and then starts to read from the local newspaper. He looks over and sees a group of teenagers drinking and proceeds to kick out Underage Drinker 1, Underage Drinker 2, and Underage Drinker 3. Roy and Mary walk over and Roy asks what the problem is. Roy tells Nicholas it is for the greater good to allow the Underage Drinkers into the bar, versus out in town getting into trouble. Nicholas kicks all of the minors out of the bar, which significantly reduces Mary and Roy's patrons. During the meeting of the Watch, Joyce Cooper tells everyone that Janet Barker had twins and then Tom Weaver moves onto the business of The Living Statue. After the recent murders, Nicholas runs to the castle and finds the NWA sitting around a circular table chanting. After the chanting, Joyce tells the others, Janet Barker has decided on calling her twins Roger and Martin. Tom tells the others that Nicholas has been killed and their next move is to eradicate the hoodie gang. Nicholas tells them they are all under arrest and Simon Skinner tells him everyone died in order for Sandford to win the Village of the Year Contest. Inspector Frank Butterman reveals himself to be a member of the group and tells Nicholas he decided on his path after his wife committed suicide after Sandford lost the Village of the Year Contest. Nicholas tells them all they are coming with him, but they pull out weapons and Michael Armstrong and PC Danny Butterman appear at his side. Nicholas grabs a knife away from Michael and threatens to kill Danny before running away. He appears to be stabbed by Danny who drives Nicholas to the edge of Sandford. The next day, Nicholas rides to the center of Sandford and he and Danny get in a shootout with Roy and Mary and they are both eventually arrested.
