Language: English
Rating: PG

Hell is being stuck with yourself when you're full of self-loathing.

Phil Connors (Bill Murray) strikes people as having a high opinion of himself. He's a Pittsburgh weatherman full of contempt for his colleagues; he's convinced he's headed for a more prominent spot on national TV. An assignment to cover the Groundhog Day festivities at Punxsutawney is a personal affront to him; he hates the yokels in small towns and their silly traditions. When a snowstorm forces him to stay overnight in Punxsutawney with his producer, Rita (Andie MacDowell), and cameraman, Larry (Chris Elliott), he's gone through what he probably considers the most pointless, boring day of his life.

Until the gets up the next morning, and finds out it's Groundhog Day all over again.

Time is stuck in a loop, forcing Phil to relive the same day over and over. At first, he thinks he's going nuts. How can it be that he's waking up every morning at 6:00 am in the same bed and breakfast, with the same song playing from the alarm radio? As he realizes that this is real, and he's actually trapped in Punxsutawney in a 24-hour loop, he begins to indulge his hedonistic side: speeding, thieving, seducing women, eating junk food the way a man would when he doesn't have to care about cholesterol and cavities.
