plot a course of action
To 'plot' is usually a plan involving a group of people which is morally dubious or possibly illegal or wrong against a group or the government. If you 'plot a strategy' or 'plot a course of action' it means you are carefully planning ahead for the action, you intend to take. You will hear these phrases use more often in professional contexts.
