"Krithyam: The Mission", directed by Viji Thampy, has Prithviraj in his first double role. 

Sandra Punoos (Pavithra), the daughter of a multi millionaire, is a wannabe writer of crime thrillers with a troubled past. She lives with caretakers Solomon and Victoria. Her best friend among many friends, is Lavanya ( Eva Pavithran) with whom she shares everything.

Once, after a queer road accident, she comes to know that she is terminally ill with some indescribable problem in her brains. Unable to bear the ultimate reality, she hires a professional killer Christy Lopez (Prithviraj) through the Internet to end her life, as she had imagined in one of her stories. She does not have the courage to kill herself. 

Then she gets a second opinion on her brains from a US-returned neurologist (Indrajith in a guest appearance), who says she is curable. Then she wants to live. Mean while Sandra meets Satya (Pritviraj), a drum player in a musical troop who turns out to be an exact replica of Christy. Satya becomes her saviour. Here onwards the story develops more twists and turns, including the identity crisis between Christy Lopez and Satya, one of them Sandra's would be killer and the other her saviour. Find out what happens to Sandra? 

Viji Thampy with the usual thriller theme fails to deliver this time. The narration of the story is clichéd. Script by Kaloor Dennis leaves much to be desired and music by Girish Puthenchery-Udayakumar team is just okay.

Prithviraj tries hard to make most out of the role of his lifetime. But he looks more a 'Style Icon' aspirant than a menacing killer with a hep beard, gelled hair and designer sunglasses. Compared to that, the performance of Prithviraj as Satya, the orphaned, speech-impaired drummer appears a potential Oscar winner!. Pavithra, on the other hand, is consistent with her portrayal of Sandra Punoos. She does not try to do anything drastic or unpredictable. She just plays it safe. Eva, daughter of director Pavithran plays Lavanya. 

Of the supporting cast, Jagathy Sreekumar and Siddique are dependable and handles their roles well. Jagathy is subdued as Solomon Uncle compared to some over-the-top acting in his last couple of films.

The film, which promises the moon, fails to deliver, especially for Prithviraj.
