Thousands of years ago, a race of beings known as Dark Elves tried to send the universe into darkness by using a weapon known as the Aether. Warriors from Asgard stop them but their leader Malekith escapes to wait for another opportunity. The warriors find the Aether and since it cannot be destroyed, they try to hide it. In the present day, Jane Foster awaits the return of Thor although it has been two years since they last saw once another. In the meantime, Thor has been trying to bring peace to the nine realms. Jane discovers an anomaly similar to the one that brought Thor to Earth. She goes to investigate, finds a wormhole, and is sucked into it. Back on Asgard, Thor wishes to return to Earth but his father, Odin refuses to let him. Thor learns from Heimdall, who can see into all of the realms, that Jane disappeared. Thor then returns to Earth just as Jane reappears. However, when some policemen try to arrest her, an unknown energy repulses them. Thor then brings Jane to Asgard to ...
Someone mentions that his old girlfriend "kept sleeping with other dudes."
A news channel reports and shows that a nude man had appeared at the Stonehenge (his private parts are pixelized, so no actual nudity is seen).

Battles are huge and relentless. In the flashback showdown between Malekith and Thor's grandfather, Bor, we see tons of flashing swords and spears and laser-like guns and reality-twisting grenades. (That latter weapon seems to suck victims into a vortex and fold them up.) A field is littered with the corpses of Asgardians and dark elves. Other melees feature the same allotment of weapons, which are always used to devastatingly lethal effect. Spaceships destroy buildings, crash and sometimes do both simultaneously causing untold (unseen) casualties.
A rock monster gets crushed by Thor's hammer. A demon-like creature forces a man's head into a force field, and we can hear his screams.
A bad guy loses both of his arms, and a good guy appears to have his hand sliced off. (We see the bloody stump.)
An evil henchman is swallowed almost whole by a strange and fearsome creature, and several more are crushed by someone throwing a car. In one melee, Thor snaps a bad guy's neck.
A demi-god and a demon get stabbed through the chest (at the same time with the same blade). A woman is run through with a sword. Someone gets pounded in the face.
The Aether is a violent substance.
When Jane has the stuff in her system, anyone who threatens her gets blown back with a mini-explosion. The substance is used to assail, toss and tumble Thor and others.
The final fight scene is very intense between Thor and Malekith ,especially when Malekith is smashed to death by one of his own ships.
Thor's hand gets cut off. It is revealed to be a hologram, and it grows back

Frigga's death is upsetting, and the entire scene is emotionally intense and sad.
The magical weapon known as the Aether takes over its users' bodies and appears as an ominous reddish-black cloud entering through individuals' eyes and mouths (changing their eye colors) and sometimes being seen moving under their skin; this may be disturbing to younger viewers.
