Frodo Baggins Timeline and Summary

Having left the Company and decided to continue the Ring quest on their own, Frodo and Sam get lost in the Emyn Muil.
Luckily (we guess) they find Gollum, who has been tailing them since they left Rivendell.
Together, they capture Gollum, with whom Frodo strikes a bargain: that he will not hurt Gollum as long as Gollum shows Frodo the way into Mordor.
As the trio travels toward Mordor, they are ambushed by some Gondorian scouts, who bring Frodo and Sam to their leader, Faramir, who happens to be Boromir's brother.
After deciding not to take the Ring from Frodo, Faramir gives Frodo and Sam provisions and advice.
Frodo and Sam leave Faramir and his men behind, leery of Gollum's guidance, but having no choice but to follow the creature.
Gollum takes Frodo and Sam high into the mountains, until they finally reach the pass of Cirith Ungol.
Gollum suddenly disappears, so Frodo and Sam proceed on their own.
Inside the dark tunnel of the pass, Frodo is attacked by a giant spider named Shelob.
Meanwhile Gollum leaps out and tries to strangle Sam.
Sam and Frodo realize that Gollum has betrayed them in an attempt to steal the Ring.
Frodo and Sam fight back as best they can, but Frodo winds up getting bitten by Shelob anyway.
Sam fights her off of Frodo, but Sam thinks that Frodo has been killed, so he takes Sting, the star-gem of Galadriel, and the Ring to continue Frodo's quest.
But when he finds out that Frodo is alive, he resolves to rescue his buddy so that they can continue the quest together.
