When an escalating gang war spills into the stands of the local high school football game, injuring several bystanders and killing a gang leader, Five-0 uncovers an unlikely partnership between Samoan gangs and a mainland mob.
Attending Steve's former high school's football game with the gang and Grace, Danny spots armed men before they shoot at players. It turns out to be a gang war between the Chinese triad and Tuinei's locally anchored Samoan gang, which is however negotiating a bloody deal with Frank Salvo's New Jersey gambling mob. Chin fails to get his dirty uncle Sid out. Steve helps Danny keep his visitation rights.—KGF Vissers
