Five-O has to intervene to prevent some rich man justice in "We Hang Our Own" and then has to solve the murder of a man who wasn't who he seemed in "The Two-Faced Corpse". Leslie Nielsen and Abe Vigoda back-to-back. What's not to love?

First Five-O deals with a senator under attack in "Bomb, Bomb, Who's Got the Bomb?" and then has to solve the mystery of a dead bank robber and the missing loot in "Right Grave- Wrong Body". Trigger warning for mental illness for "Bomb, Bomb, Who's Got the Bomb?". Minor trigger warning for suicide for "Right Grave- Wrong Body".

Five-O contends with a clever killer recreating solved murders in "I'll Kill 'em Again" and then take on a deadly fencing operation in "Pay Now- Steal Later". It's Casey Kasem in some incredible sport jackets and Ray Danton shirtless. The best of both worlds. Minor trigger warning for suicide for "I'll Kill 'em Again" if you watch the episode. I don't mention it in the discussion.

Season 7 kicks off with a radical group committing mayhem in "The Young Assassins" and extortion via volcanic eruption in "A Hawaiian Nightmare". Also my periodic reminders. Let's have some fun!

Season 6 ends with Five-O tying to catch a brazen thief in "30,000 Rooms and I Have the Key". Stick around for the season wrap and my unofficial, unnecessary tallies.

Season 6 begins to wrap up with Five-O receiving an unwanted helping hand in "Mother's Deadly Helper" and then Steve, Danny, and Duke take a cruise to catch a murderer in "Killer at Sea".

A murder turns Five-O on to an elaborate gold plot in "Murder with a Golden Touch" and a serial killer rapist is on the loose in "Nightmare in Blue". Trigger warning for sexual assault for "Nightmare in Blue".

Both a hitman and Five-O are looking for the same guy in "Secret Witness" and a young man with daddy issues is cooking up drugs with a vengeance in "Death with Father". Trigger warning for suicide for "Death with Father".

The back half of Season 6 continues as Five-O surfs for a hitman in "The Banzai Pipeline", and then hopes to con a con artist in "One Born Every Minute". Mild trigger warning for suicide for "One Born Every Minute".

Five-O is in search of five cents in "The 100,000 Nickel" and then try to track down clever bank robbers hiding in plain sight in "The Flip Side is Death". Come for Victor Buono, stay for the 8-track tapes.
