Group 35 encountered zombies while walking through Southampton Common and had to flee towards the lake. They discovered the zombies could walk under water, cutting off their escape route. They took refuge in an abandoned pub, barricading themselves in for 5 days until the zombies broke through. Two more survivors then joined the group, who split up to retake the pub supplies and hold the Bargate Gateway. After six weeks, the group had learned to travel at night when fireworks were most effective at distracting zombies, who could only walk at 2-3 mph.
