Boomtown

Investigating the brutal murder of a homeless man bludgeoned to death with a brick, Joel and Fearless follow up on a tip from Teresa and discover two filmmakers who pay vagrants to become would-be gladiators and battle each other in the park; when the detectives realize that the filmmakers bribed a homeless drunk to land the fatal blows, they team up with Tom and David in the search for evidence to convict them.
