Be careful what you wish for. Obsessive thriller classics Fatal Attraction and the Hand That Rocks the Cradle get flipped upside down by the Australian nail-biter Coffin Rock. Instead of a disturbed woman, this time it's Irish drifter Evan (Sam Parsonson) who becomes madly possessive about a lover and a child. Jess (Lisa Chappell) and Rob (Robert Taylor) are the happily married couple beset by only one nagging problem: they can't get pregnant. After a drunken fight, Jess wanders off and into the arms of the loner Evan. Evan has other plans and suddenly one night of infidelity produces a stranger at the door - and perhaps even in her belly - that tests not just their marriage but their ability to survive. From the producer of the smash worldwide hit Wolf Creek, this is smart and substantial suspense about the terrifying effects of one single mistake.
