一个刚刚离异的男子试图找寻曾经的这段婚姻中还令他无法割舍的唯一一样东西：歌利亚，他想念的猫。

Alpha Gang are aliens, sent on a mission to conquer Earth. Armed and dangerous, they show no mercy, until they catch the most toxic, contagious human disease of all: emotion. Their plans for world domination are in danger of derailing once they start to feel joy, fear, empathy and, worst of all, love... but hopefully they can still annihilate mankind before it's too late.
