Firstly, the product description Amazon have provided is incorrect: the plot involves Clint, an every day working man and his wife Joanna, who is having an affair with a doctor. They plot to kill Clint and get the insurance money. They poision Clint, and he is buried alive (as the title may have given away). What follows is a set of circumstances that teeter on the edge of plausibility... i'll say no more so as to not spoil the fun.
I first saw this TV movie in the 1990s, and have loved it ever since. My VHS recording is looking a bit sorry these days, so I was over the moon to see it had finally been released on DVD.
I feel like I have to qualify this by warning that this is a cheesy TV movie - don't expect a masterpiece. The plot is ludicrous, and it is fairly cheaply made. Still, it benefits from a damn fine cast (Atherton is especially great as the doctor), and some sturdy direction. The major plus for me is just how much fun this - if you go in expecting the Shawshank Redemption, you'll be disappointed. Take it for what it is, and enjoy.
