The .acsm file is actually just a "pointer" file that tells Adobe Digital Editions which .epub file to download (and authorizes it to do so). If you have Adobe Digital Editions installed and you double-click the .acsm file, ADE will dowload the .epub file and you can try to run that .epub file through Calibre. The .epub files, however, are copy-protected, and I belive this will prevent you from converting it.
In short, I do not think you will be able to read this book on your Paperwhite. If you have another portable device either made by Apple or running Android, you can install the Overdrive Media Console app, and read the .epub file in that app.
Please let me know if you have other questions.
