Series three ended on a cliff hanger with Janeway on a Borg cube and Harry infected by Species 8472. As series four opens and this story concludes Tuvok joins the captain on the Borg cube where they work with a Borg designated Seven of Nine to create a weapon that can defeat Species 8472. Before they can complete their task they are attacked and the cube is destroyed but not before the captain, Tuvok, Seven and a few other Borg drones can beam over to Voyager. While she may have survived the attack Janeway was injured leading to Chakotay taking command. As the Borg try to open a rift into the space occupied by Species 8472 he opens an airlock flushing most of them into space but Seven manages to hold on and Voyager ends up through the rift where they find out whether or not their new weapon will work.
This was a good episode that introduced the first new member of Voyager's crew since the first episode, unfortunately the opening credits suggest that one of the main characters won't be around for much longer... so if you don't want to know who is going soon avoid reading the credits. As well as plenty of action there are some good character based scenes, especially the talk between Janeway and Chakotay where she clearly isn't pleased with some of the decisions he made while she was incapacitated.
