New girl Leslie meets poor boy Jesse.
They become friends and create an imaginary kingdom in the woods called Terabithia.
One day Jesse leaves Leslie to go on a trip to the city without asking her to come along.
She goes to Terabithia by herself and drowns in a creek. He blames himself for it.
He eventually comes to terms with Leslie’s death; and creates a bridge over the creek to Terabithia, so no one will fall in the creek again.
He then shares the magical kingdom with his younger sister.
