Olivia Goes West is a American animated adventure crossover movie with the An American Tail trilogy and 1986's The Great Mouse Detective. This will be released by Walt Disney Studios Motion Pictures and Amblin Entertainment.


A year has passed since Basil's battle with Ratigan atop Big Ben, and the Flavershams have moved to the American West to put that horror behind them. However, once arriving in Green River, Olivia's father is kidnapped once again. Can Olivia hone her detective skills to find him? Luckily, she'll get a little help from one Fievel Mousekewitz, setting the two of them off on a journey that will include many old friends and foes alike.

Little do the two of them know that Ratigan survived the fall from Big Ben, and has teamed up with Cat R. Waul in a scheme to take control of Green River, and eventually, the United States.

The story takes place four years after Basil's American Tail, in 1890. This creates an alternate timeline in which the events of The Great Mouse Detective were moved back eight years to 1889.
