J.R. gets Cally into bed, but when J.R. is discovered by her crazed brothers, he is arrested and convicted of rape. After Cally's brothers break J.R. out of prison, Cally lies that she is pregnant, and her brothers force J.R. into a shotgun wedding. J.R. eventually escapes from Haleyville and returns to Dallas, but Cally follows him. She intends to make their marriage work, but finds that J.R. wants nothing to do with her.
