In the Chicago offices of Promethium Pharmaceuticals, co-presidents Richard Rusk and Elaine Markinson receive a call from a company employee, Harold Soyinka, who claims he has been kidnapped in Mexico and that his abductors are demanding a ransom of five million US dollars. One day earlier, Harold, Richard, and Elaine arrive in Mexico where they meet Sanchez, head of Promethium's Mexico plant. Unbeknownst to Harold, it is revealed that Sanchez has been selling Promethium's latest product, medical marijuana in the shape of a pill, to a Mexican cartel. Promethium has decided to cut them off to avoid harming their upcoming merger. Later that evening, as Richard, Elaine and Harold have dinner, Harold secretly records Richard's and Elaine's conversations while he is away from the table. He learns from the recording the merger plans, which would result in Harold losing his job. That night, he also discovers that his wife is having an affair and wants a divorce. Sanchez informs cartel leader Villegas about them getting cut off by Promethium; Villegas maims Sanchez and, believing that Harold is Promethium's boss, orders his capture.
