Indiana Jones and the Kingdom of the crystal of skull

We rented this movie the other night to watch it. The movie starts out with no plot what so ever! The beginning starts in the middle of no where in nevada at this secret army base. These russian characters come out of no where and take control over what they are there to get. Indiana Jones is there with his friend who turns his back on him. It turns out that his friend nick is a spy and has been against him the whole time. Jones is there to show the russians this silver magnetic bomb type thing. Jones escapes from the Russian group by going in the speed bullet across the desert. He is a professor at a college when his son who at the time he does not know who he is. this kid asks him to come to help him find his mother who happens to be Jones old wife. They go on this excursion in Peru to find his mom and this missing skull. Some one has stolen this skull and misplaced it. They are set out to put it back. Throughout the movie there are chases with the russian group and Jones and his group. The movie is packed with action and adventure and is set towards the "corney" crowd. The movie was some what good, but i would not recommend it.
