When his buddies desert him in law-enforced territory, a fast-talking space pirate hitches a ride with an underpaid traffic officer to retrieve his precious loot.

I can't see enough action to fill a whole act 2.

He hitchhikes a ride with the officer,?but?then what happens?
They sit in his space car for 50 minutes until they find the bad guys? What is the resulting action?

Films are often sold on the action of act 2 as it is most of the film, best if you describe how he plans on getting back the loot - fight, steal or con his way to it.

"disgruntled in place of underpaid"

Example:?After his cargo is stolen, a suave space pirate convinces a disgruntled,?underpaid traffic officer to give him a ride so he can retrieve his loot.?(~26 words)

I'm not sure if stating it was his friends is necessary; unless they are the actual antagonists of the story, then it might be best to leave them out to cut down the word count. I suggest just focusing the logline on the MC and the traffic officer. I don't think you even need to mention an antagonist in it because it seems as though the antagonist doesn't exactly surface until later anyway. The MC's goal is clear.

I have to agree. If his friends are the ones who steal the cargo then it needs to be said in the logline... not "when his buddies desert him..." but "When his Buddies steal his cargo..."
