If I explained the implausible storyline of this film to you, I know with absolute certainty you'd say 'that's so dumb' so I'm not going to bother.
Just know it somehow stars talented actors like Ellen Burstyn and Harrison Ford and yet it induced derisive laughs from the group I watched it with. Actual laughs, guys. And not in a good way.
If you are interested in how silly the story line is, I will break it down for you below.
