Out of Bounds, also known as Dead in the Water, is a 2003 British psychological thriller film starring Sophia Myles, Celia Imrie and Sophie Ward.

[1] 18-year-old Louise (Myles) is stuck in a run-down girls' boarding school and can't bear the thought of being away from her lover, art teacher Matthew (Asprey), during the half term break.

But when Matthew's wife, Veronica (Ward), who is also the school's headmistress, finds out about the affair, she is driven over the edge and stabs him.

Trapped in the remote school and haunted by nightmares, Louise finds the vast Victorian building a spooky shell without the other pupils.

Scared and excited, Louise rushes to meet him, but it is only as his arms encircle her that she realises her eyes were deceived, with terrible consequences.
