Nicholas Angel (Simon Pegg) works as a senior patrolman in London. Catching thieves and solving cases seems to be his greatest pleasure. For this reason, he became the most dedicated and capable police officer in the police station. But this aroused the jealousy of the sheriff, and poor Nicholas was transferred to a remote and quiet town to be a policeman. The town has not had any vicious crimes for decades. Nicholas lived quite depressed there, and he felt that his ability to catch thieves had no room to display. What bothered him even more was that Danny Bateman (Nick Frost), the son of the town police chief, also came to join in the fun and became his partner. This new partner was extremely troublesome and asked about the experience of police officers in big cities all day long. Just when Nicholas was worried about the trivial affairs in the town and his partner, a case happened in the town, which made Nicholas smell an opportunity to show his skills, and a thrilling battle began.
