When an unorthodox AFP detective, with a confrontational personality, uncovers an operation of a Mexican drug cartel in Australia. He must now stop a one ton inbound shipment of heroin with the help of an uptight FBI agent after the same gang.

When an unorthodox?detective from Perth's ?confrontational personality?lands him in?a drunken brawl with a bunch of Mexican drug cartel members,?he pulls his gun and is tipped on a? scheme involving?a??one ton inbound?shipment of heroin .? Now he must?work with an uptight FBI agent who happens to be his one night stand to?stop them.

That really leaned up the logline thanks for that.

The re-write provides a better motivation for the Mexican and the FBI agent to be in Australia. The hook for me in the concept would be the Mexican hombre hiding out in Australia. That's different -- but not implausible.

How about something like:

An unorthodox AFP detective must collaborate with an abrasive FBI agent to catch the notorious head of the most violent Mexican cartel who is hiding out in Australia.

(Maybe use other adjectives to describe them -- but, ideally, only 1 adjective per character.)
