It stars Ioan Gruffudd as Solomon Lewinsky, an Orthodox Jewish man in early 20th-century Wales who falls in love with a gentile woman named Gaenor Rees, played by Nia Roberts.

[3] In 1911, Solomon Levinsky, a young Orthodox Jew, lives with his Yiddish-speaking family in the South Wales Valleys.

One day, Solomon meets a demure, young gentile woman named Gaenor Rees and instantly falls in love with her.

Gaenor's father, Idris, finds the red dress and demands to know who gave it to her.

Knowing his own family will never accept him being with a gentile woman, Solomon hides the relationship at home.

Burdened by this secret, Solomon begins to struggle with his faith and feels distant from his family.

Gaenor's brother, Crad, invites Solomon for a drink with his friends and teases him about being a peddler.

Before going to see Gaenor, Solomon always hides his tzitzit in a wall, but this time he is unable to find it.

Gaenor becomes frustrated with Solomon's unwillingness to introduce her to his family and tells him she feels like she means nothing to him.

One day in chapel, a fellow worshipper named Noah Jones accuses Gaenor of being pregnant after "fornicating with an outsider."

When asked by the Minister to confirm or deny the accusation, Gaenor admits to the whole congregation that she is pregnant.

Solomon faces harsh conditions and is ill by the time he reaches Gaenor at her aunt's.
