欢乐喜剧人第四季Al Shines，这位“US race car track circuit”的前冠军，自从失去赞助商罗宾，他的车队组建越发艰难。罗宾选择了Al的不成熟的女儿作为替代。　　Al Shines, former king of the US race car track circuit, has a hard time starting his own team, once he's fired by his sponsor Robin Cates. Robin hired Al's immature daughter Kylie Shines instead. She resents Al's inevitable 'absence' as a widowed father, as well as the reigning champion, equally young but professionally vetted Kid Walker. Kylie tries to prove herself against Kid while having an on-off affair with him. Cates's marketing strategy dictates his intentions to manipulate Walker and both Shines racers.
