All plots must have conflict. Without a rising ation and climax our story wouldnot go any where or result to anything. The steps are exposition, rising action, climax, falling action, catastrophe and resolution.
A plot can be both without action and dialogue it is not common but it can be done, but it is essential to have conflict or you don't have a plot at all.
Hope this helps, if you need anymore help or further explanation just let me know! :)
Chicken because a can is where the coup came from.
