When a contract killer murders the wrong person, he must hire a body guard to protect himself from his own employer.
One more thing, in the movie “The hitman’s bodyguard” The goal was to get the hitman to a trial, to put away some very bad people. A proactive goal. This would be a good example of what I was talking about above; about a pro-active goal for your lead character.
Agree with Richiev. It’s better if the logline frames the plot with the protagonist having a proactive goal. Hiring a bodyguard seems to put the bodyguard in the pivotal role, the key character in how the plot plays out. The hitman comes off as weak, appearing to hide behind the bodyguard.
