Stanly (Tom Arnold) unencumbered by common sense logic is able to see the evil underlying plots surrounding his family. And being a man of action is determined to get to the "bottom" or at least stop them. Someone is stealing his garbage in the middle of the night and letters are being pilfered by the Evil Sender (Christopher Lee). On the way he meets many interesting people and even The Lloyd (Frankie Faison). Worried about his being and where abuts the rest of his family follow in his foot steps. Worried that Stanly knows too much aliens pick their nose.
One of my favorite scenes is where Stanly connects with a car battery and gets his brain cells charged; for a fleeting moment he sees everything as we do and wonders how he got into the fix.
