Upon his death, Arnold marries his lover, Karen, in spite of his widow, and leaves deathtraps accompanied by audiotapes and his preserved and articulate corpse for those who cared only for his money.
When wealthy, eccentric Lord Arnold Dwellyn dies, his funeral also doubles as a wedding: Arnold gets hitched to his mistress Karen, who will inherit his vast estate…if she agrees to meet several conditions. This includes remaining in his mansion with Arnold’s corpse by her side. Karen—along with Arnold’s ex-wife, his brother, and several members of his family—are unhappy with this arrangement, but desperate to get their hands on Arnold’s vast wealth, which allegedly includes a pile of money hidden somewhere on the grounds. But as each of the guests attempt to break or subvert the conditions of Arnold’s will, the consequences end up being lethal and Karen finds herself caught up in a series of grisly murders. Has Arnold returned from the dead to take revenge on his greedy loved ones, or is there a living, breathing killer lurking around the mansion?
