Joe Mannix is called by an old friend named Rudy who is an executive with Majestic Studios, about the studio's big star, Mitch Cantrell. Cantrell is both obnoxious and reckless, but Rudy's concern is that someone has been threatening Cantrell's life -- threats that appear to have come true when someone stretched a metal wire across a road in front of Cantrell's motorcycle. When the attempts on Cantrell's life begin to multiply, Mannix tries to convince Cantrell that he needs to take precautions, but Cantrell refuses. Mannix nevertheless stays on at the studio, hoping to find the person behind the threats on Cantrell's life. Written by aldanoli

Wow....Robert Conrad really plays a HUGE jerk in this episode! Such a big jerk that you wonder who WOULDN'T wan to kill him?!
23 October 2013 | by MartinHaferSee all my reviews

Robert Conrad is the guest star in this episode of "Mannix" and unlike the usual guest stars, he completely upstages everyone. Now I am NOT saying it's because he overacted but because his character is a bigger than life jerk--a guy you just love to hate! And, wow, does he play him with a gusto!!

The show begins with an attempt on Mitch Cantrell's life. Mitch (Conrad) was apparently the object of the attempt yet, inexplicably, he seems completely unconcerned. So it's obvious HE didn't hire Joe Mannix to investigate. However, the studio doesn't want to lose their big star and they pay the the investigation--though considering how difficult Cantrell is, you really wonder why they bother! It's because Cantrell is so self-absorbed and awful, you'd think they'd WANT him to die. In fact, EVERYONE in this film hates the guy, and so it's tough for Mannix to solve a case where EVERYONE could easily be the assailant!

I really liked this episode--and it's one of the best of the series. In addition to a neat plot, the characters are fascinating and the twists quite satisfying. Well worth your time....and a case that Mannix probably DIDN'T want to solve!

Best lines from the show:

Mannix: "You're losing friends, Mitch"

Cantrell: "I'll buy a bushel more!"
