"Walk on Water" is an intriguing thriller that contains an odd love story, and features a Mossad agent who is plagued by guilt when he unexpectedly gets attached to the relatives of the man he is hired to kill. The plot is never predictable, and the story takes a few unexpected twists and turns.

The film takes place in Berlin and Israel. It indirectly explores the themes of Jewish identity and duty to Israel. It also is a cautionary tale aimed at people that are obsessed with the past.

After the unexpected suicide of his wife, Eyal will do almost anything to occupy himself and forget his pain. He agrees to assassinate Alfred Himmelman, a Nazi war criminal who has been living in South America. Himmelman is set to be reunited with his family at his dad’s birthday.

In order to get to Alfred, Eyal is ordered to infiltrate the Nazi’s family. He becomes the tour guide for Axel, Alfred’s great grandson, who is unaware of his family’s dark secrets. When Axel goes to visit his sister Pia, Eyal shows him around. He spends a lot of time with both Pia and Axel, and he brushes off Pia’s non-aggressive advances. Eyal is also introduced to Berlin’s gay culture through Axel, and he begins to rethink some of his narrow views on homosexuality. One of the strangest and most joyous scenes is a gender bending, karaoke duet involving Pia and Axel.

Lior Ashkenazi is ideal for the role of Eyal. He initially has some of the cool detachment that Alain Delon exhibited in the classic French assassin thriller, "Le Samourai." Eventually, as his character becomes more and more torn between guilt and duty, he becomes more fully human.

The film reflects the Israeli military background of the director, Eytan Fox. Although he was born in New York, he moved to Israel and even served in the Israeli army. He eventually became a filmmaker and did the creatively well received " Yossi and Jagger."

"Walk on Water" is an intelligent and original film that is grounded in strong characterizations. It also avoids a feel good Hollywood ending, and it is consistently absorbing.
