Pieces (1982)

While Timmy is enjoying his time putting together a jigsaw puzzle of a naked lady, his mom walks in, commences  screeching and smacking him around.  Timmy reacts as any child would by killing his mother with an ax and blaming it on an intruder.

Forty years later, a serial killer is targeting college coeds and stealing different pieces of their bodies. The killings get rolling right along with two of them within the first ten minutes of the film. Now that's a way to start a movie.

The police decide to send an undercover officer to the campus  and assign Mary to be the girls tennis coach.  She'll be partnering with a student named Kendall, who is supposed to be a stud, but is more nerdy looking than handsome.

There are tons of nonsensical things in this film, including the ending.  It's just ridiculous.   But it does have Christopher George in it, so that's a plus.

Ridiculous dialogue-

"We don't have any more time.  Take some uppers or something."  - Detective
