Flashpoint is a great series, and if you really want to know about the show - read some of other user reviews.
Instead, I am here to confirm what this season contains. There is a lot of confusion between Seasons 2/3 in USA and Canada. So to clear it all up:
-- If you buy this Complete Season 2 from Amazon.ca (barcode ends in 56740, release date is 2010, running time is 760minutes), then you are getting the complete CANADIAN season 2. Which means episodes starting at "Business as Usual" and ending with "Behind the Blue Line". So this is the COMPLETE season 2 from Canada --
If you are confused about the seasons, just check out this Wikipedia page, it lists things very clearly.
The USA seasons are all out of order and messed up, so it is highly advised to get the Canadian version of Flashpoint seasons (you can tell by the cover, and it is produced by CTV and Phase4Films).
Hope this helps! :)
