Step Brothers is a very hilarious movie that is about this guy that falls in love with this lady. She is scared to tell him that she has a thirty-nine year old son that still lives with her. She is relieved when he says that he has a forty-year old son that still lives with him also. The main point is that the sons, Dale and Brannan do not like each other at all in the beginning. They threaten each other in funny and inappropriate ways. At the end though they get along perfect just like normal brothers but there parents get a divorce. This big change in their life has made them grow up to their age level and got great paying jobs and became very successful.
