The Story of Sing concludes with a multi-purpose road trip to California. First stop, a visit with Sing's brother, Jacko, in his new profession as an assistant animal trainer. When Natalie the chimpanzee escapes and ransacks a grocery store, Sing is enlisted to assist in the animal's capture which turns out to be a bigger adventure than what he bargained for.
Next stop, a date to meet the parents of his client and friend, Hailee Morgan. Originally hired as Hailee's bodyguard, the relationship between Sing and the beautiful Hollywood actress has evolved well beyond being strictly professional. It soon becomes apparent that this wealthy family is manipulating Sing to carry out an agenda that places him in an awkward position.
The third leg of Sing's journey takes him to San Diego where his best friend, Trent, suspects a shipment of yellowcake uranium is scheduled to be smuggled aboard a cargo ship owned by the mysterious underworld figure, Uncle Sam. Trent hires Sing to investigate whether the contraband is destined to be processed into a weapon to be used against the United States.
When Sing interferes with Uncle Sam's plans, the resulting backlash impacts everyone close to him and provokes a final confrontation with Sing's enemies and also with his feelings for Hailee.
He can triumph. If he is Brave Enough
