Tonight 50 years ago, CBS aired S06E10, "A Bullet for El Diablo".

One of the weaker episodes from Season 6 involves the two daughters of dictator Emilio Ramos (Richard Angarola). Edith Diaz portrays both Maria and Rita.

Maria is a meek thing attending university in Honolulu. Rita is her illegitimate half-sister who has been living in Hawaii forever. The biggest problem is that they look exactly alike. I have 4 half-sisters, none of us look anything alike.

Anyway, Rita is hell-bent on revenge against her father and sees Maria as the perfect target. Rita recruits Pepe Olivares (A Martinez) and Carlos Rojas (Richard Yniguez) to kidnap Maria and hold her for ransom.

Five-O becomes heavily involved when Ramos arrives in Hawaii demanding to know why they haven't handled the situation. McGarrett immediately butts heads with Ramos as it becomes clear things are dealt with differently in Ramos' country.

When all is said and done, Rita changes places with Maria and kills her father. The kidnappers want a plane to leave the island and there is a serious time crunch. However, nobody gets away with anything and Maria is rescued.

Mr. Mike's review does an excellent job of breaking down the episode. It's here: https://www.fiveohomepage.com/5-0log6.htm#130

There isn't much I like about this episode except to see some early work by A Martinez. I first saw him in the soap opera "Santa Barbara" (don't judge – I was a teenager!). I have seen him in several other works including an emotional role in "CSI: Crime Scene Investigation". He was a father whose son was killed for his bicycle when a criminal was trying to flee from police. It was gut-wrenching.

The whole half-sister but they look alike thing puts me off. They could have solved the issue in any number of ways, such as what Mr. Mike proposes in his review. Because of this issue, I can pass on this episode and be okay.

Regardless, Happy 50th, "A Bullet for El Diablo"!!!
