Kurt (Jason Sudacis Jason Sudeikis) was regarded as the successor of the company, but the boss died suddenly. His son Bobby (Colin Farrell Colin Farrell) took over the company without authorization, triumphantly exerting his second ancestor spirit and was about to bring down the company. Three old friends who were frustrated by the evil boss gathered in the bar and decided to kill the boss together on a whim, and the three people avoided their own boss respectively, so they could escape the suspicion and achieve the perfect murder.
