Kishkindha Kand is one of the seven kands in Valmiki's Ramayan. The Kand involves the meeting between Lord Rama and his disciple Hanuman. It also features the story of two vanar brothers Bali and Sugriva and how Rama killed Bali who enslaved Surgriva's wife. It was in Kishkindha Kand that Jambvant made Hanuman realise about his strength, powers and capabilities.
Ravan kidnapped Sita and was taking her to Lanka. Sita threw her jewellery along the way to leave a trail. Some of these jewels were found by Monkey King Sugriv.
On the quest to find Sita, Ram and Laxman reached Malay parvat where they came across Sugriv, who was hiding from his elder brother Bali.
Sugriv gave Sita's jewellery to Ram and told him about his brother's atrocities. Ram helped monkey king defeat his brother.
Then, Ram and Laxman left to look for Sita with the help of Sugriv and his monkey army.
There was an ocean on the route. When Hanuman tried to cross it, he was interrupted by Surasa. Hanuman intelligently shrunk in size entered her mouth and exited. Surasa accepted her defeated and allowed him to go.
