The hybrid soldiers are pushing the residents of Homestead from the harbor to the water and Dave calls the Air Force. Tom and Russell try to stop the hybrid while Szura flees with the hybrids, Mariel and four pregnant women. Tom and Russell hunt him down and they find Szura in a hideout that Tom knew. There is a showdown between Tom and Szura. Russell helps Mariel to bring the pregnant women to the water. Meanwhile, Brett and a partner go to Underlay's home to kill Tom. They capture Larkin, Jess, Kira and Rose while waiting for Tom. When he arrives, a tragedy occurs.
"The Last Wave Goodbye" is the last episode of the First Season of "Invasion" and consequently from the whole series since the Second Season was never made. The plot ends in a cliffhanger where the viewer does not know the fate of Larkin. There are also several unanswered question about the fate of Homestead or other important characters. This series is too weak, I agree, but if the producers should have ended with another episode or a movie. Leaving the way they did, shows a great disrespect towards the viewers. My vote is five.
Title (Brazil): "O Último Adeus" ("The Last Wave Goodbye")
