Three crimes, two detectives, one continuing argument... Vexed, a brand-new, glossy, fast-paced comedy drama, revolves around Kate and Jack, a detective duo with real chemistry. They may be cops but Jack and Kate suffer the same frustrations, preoccupations and insecurities as everyone else. Always on the move or in their unofficial office - the local cafe opposite the police station where the coffee and gossip are better - their cases say something about modern life in a fresh and entertaining way. In episode one Kate and Jack attempt to catch a murderer who is using a supermarket loyalty card scheme and customers' purchase histories to pick out victims. However, while Kate uses the case to see whether her husband is having an affair, Jack decides to use the investigation and database for other purposes - his own love life.
