This movie (original German: Lola rennt) is fast paced starring Franka Potente who came to American attention a few years after this film as the girlfriend in the Bourne Identity movies.
In this story, Lola is desperate to get some money to bail out her boyfriend who has gotten into trouble. The contingency of history is explored by allowing a sequence of events to play out again and again by going back to a specific moment and starting over. The primal scream sets the process in motion. As it deals with love and parenting, some of the moments are quite moving.
It is fun to watch and makes one think about how portentous even a small turn of events can be.
