Middle-aged low level stock brokers and best friends, meek Richard and assertive Michael, celebrate Richard's birthday. Richard suspects that his wife Joyce is cheating on him. Michael proposes a get-rich-quick scheme to him. If they kill a rich guy called Joseph Campbell, short-sell his stocks and buy majority share in a biotech firm called Dinogenics, they'd be rich. Richard doesn't like it but Michael insists that it's a good idea. Richard tries to kill Campbell but can't bring himself to do it. However, corrupt Securities and Exchange Commission officer and Richard and Michael's frienemy, Sam, kills him instead. This sets off a chain reaction that leads to more murders, double crosses and plot twists.
