Coffin

Sean Justice jolts awake from a dead sleep. It's pitch black. The box he's in is wooden, with rough edges. After feeling around, he realizes he is not alone. A woman lies beside him, unconscious. He knows who she before even laying eyes on her. After finding a flashlight in the coffin, Sean explores his surroundings: a wooden box about the size of a queen-sized bed, with only two feet of clearance. Then he sees it. A video camera in the corner, next to extra batteries for the flashlight, a cell phone, and a note. And that's
when the woman, Rona Samms, awakens.

Jack Samms arrives to his luxurious home only to be surprised by a masked intruder - who identifies himself only as ‘Trick.’ Trick reveals information about his wife, Rona. Trick details to Jack why he is there and produces a video feed from a camera. The video feed shows Jack's wife and her lover, Sean, trapped in a wooden box that is buried at an undisclosed location.

Sean reads the note to Rona. It details how they only have two hours of air left and they are buried six feet under at an undisclosed location. And the cell phone they have is designed to only receive calls, and their video feed will be shown to one person. From there, the two lovers have to concoct a plan to try and escape. All of this is shown to Jack, while Trick reveals his scam. The puppet master has set a plan in motion to pin
the murders on Jack unless the wealthy tycoon pays a large ransom in exchange for the location of the 'coffin'.

A cat and mouse battle of wits ensues between Jack and Trick while the clock ticks on Rona and Sean. When Jack escapes and calls the cell phone in the box, he attempts to find the wooden prison on his own. But soon, Trick finds him and forces Jack to pay in an unexpected way. When the location is given to Jack and he races against time to save his adulterous wife, he is in for the shock of his life.
