Modern Problems tells the story of Max Fiedler (Chevy Chase) a man with a far less than perfect life. His girlfriend, Darcy (Patti D'Arbanville), left him for another man, and he can never seem to find anyone else. He comes to realize that the problem is his constant clinginess and jealousy. He doesn't have the guts to stand up to his tormentors and ends up letting them ruin his life. It doesn't help that wherever he goes, he seems to see Darcy in the company of other, better looking men. This all changes when a tanker truck carrying some sort of strange goo crashes into his car and coats Max with the mysterious green substance. He wakes up the next morning with telekinetic powers. With this new gift in hand, Max goes off to find all of the bullies that have tormented and ruined his life and put them in their place.
