Lancer was poisoned by the canister she was hired to steal. The runners healed her and planned to escort her to meet her Johnson, but were beset by rival shadowrunners, the 405 Hellhounds and toxic spirits. Not to mention that her Johnson turned out to be a toxic shaman that planned to use the poison to kill the democratic candidate and an entire stadium of his supporters. The runners were not down with that. They killed the shaman and saved (most) of the crowd.
