"The Empire Strikes Back", also known as "Star Wars Episode V: The Empire Strikes Back," is the first sequel to "Star Wars." ESB (abbreviation for "The Empire Strikes Back") was released in May of 1980. The events depicted in the film take place three years after "Star Wars."
The film starts off on an ice planet in the Hoth system called Hoth. The Rebel Alliance is stationed here hiding from the Empire in hopes of regrouping and coming up with a plan to beat Vader and his minions. When Luke goes out in search of a probe droid that landed on Hoth, which Vader sent out to search for the rebels, he gets attacked by a wampa. The wampa then drags Luke back to its lair and hangs him upside down.
Meanwhile Han is worried that Luke has not come back so he sets out in a storm to find him. Han finds a nearly frozen to death Luke, who escaped from the wampa and started the trek back to the base before collapsing, and using Luke's lightsaber slices open his tauntaun then puts Luke in there to keep him warm.
After they are rescued and Luke recovers the Rebel Alliance is attacked by the Empire after their base is found. During the battle the high profile people of the Rebellion are shuttled off the planet before the Empire takes over the base. Most everyone has left the base by then with Han, Leia, Chewbacca, and C3PO in the Falcon trying to escape Vader's pursuit of them. Luke and R2D2 have gone in search of the Jedi Master Yoda on Dagobah.
On Dagobah Luke found Yoda who taught him the ways of the Force. Until he sensed that his friends were in danger and decided to leave. Yoda tried talking him out of it but Luke promised to return to finish his training after he helped his friends.
Meanwhile Han and the crew in the Falcon went to Cloud City which was run by Han's old friend Lando after escaping Vader. But it had all been a trap and they were caught by Vader. Vader froze Han in carbonite before handing him off to Boba Fett and kept the others prisoners, while waiting for Luke.
When Luke arrived he confronted Vader and they began a lightsaber duel. As this was happening Lando, Leia, Chewbacca escaped in the Falcon. During the duel Vader got the upper hand and chopped off Luke's hand. He then told Luke that Obi-Wan had lied about his father because he, Vader, was Luke's father. Luke screamed and threw himself down the shaft in the middle of the city where he and Vader had been fighting.
As he came out of the city he landed on an antenna and used the Force to reach out to Leia to help him. So they turned around the Falcon and rescued Luke before leaving.
"The Empire Strikes Back" is a great movie and arguably the best movie of the saga because the way they end it with the "good guys" losing and the "bad guys" winning makes you think that maybe the Rebel Alliance has bit off more than it can chew.
The movie is worth watching with your family and isn't too bad for young children who will enjoy it immensely.
