So the story follows the original Kevin McCallister (Macaulay Culkin). Years after the original all grown up now Kevin has fallen on hard times and began squatting in his parents old home. His siblings who are unaware that Kevin has been living there had sold the house after the death of their parents. Kevin believes the home is rightfully his and never signed on to the selling of his childhood home falls back to his childhood memories of defending his home from “intruders” as the new owners and the law try to survive the traps laid by Kevin. (This is what I have so far I have the story ending on a hopeful note where his siblings find out and there a touching moment where they get him help and he can turn his life around.) (Feel Free to add actors you think could fit outside the the McCallisters if you can.)
