The group is facing a severe water shortage with only about six weeks' worth left.

Victor suggests going to a dam to get a permanent solution for their water needs.

The group plans to travel through a sewer tunnel to avoid walkers and reach the dam.

There is skepticism about Victor's navigation skills and trust issues among the group members in the tunnel.

Victor reveals that he used Ofelia as bait in the past and had a conflict with Daniel.

Daniel is at the dam, and he has a complex relationship with both Victor and Madison's group.

Madison tries to negotiate a trade of resources for water with Lola, who initially refuses.

Lola refuses the trade due to the risk of revolt from her people and the complexity of their situation.

Walker decides to leave, believing that the ranchers must go due to limited resources.

Lola eventually agrees to provide water to Madison's camp after seeing their dire situation.

The arrangement is for 10,000 gallons of water per week until the rains come, with a tanker to be sent as a show of good faith.

Victor orchestrates an explosion at the dam to create an emergency, forcing Lola's hand in the water trade.

Madison struggles with her decision but ultimately wants to stay at the ranch despite its challenges.

Daniel is wary but relieved to learn Ofelia is alive and with Madison's group, and agrees to the water trade.

The explosion at the dam is a strategic move by Victor to ensure the success of the water trade.
