I find the logic of the premise confusing.

Did they hide the drugs inside seagulls in hopes they would fly to the correct place but the drugs seeped into the seagulls killing them in the process?

If so is that a critical element of the story that needs to be in the logline? Could it just be described that she needs to retrieve the load of drugs or shipment or loot.

Are her mates being implicated as criminals to the police? Are they under arrest and therefore can’t collect the drugs them selves to pay off the debt making her the only one on the outside that can? How would paying off the debt to the other drug dealer help her help her mates in custody?

Are her mates being implicated as the dealers who screwed over a bigger drug dealer? If so why can’t they collect the drugs them selves to pay off the debt why are they relying on her to do so?

Perhaps a change to the semantics could help clear this up. “Implicated” sounds like a legal term combined with the fact that she has to get the drugs back suggests that they are in trouble with the law but paying back the debt logicaly suggests they are in trouble with the other drug dealer.

Lastly I personally would find it hard to empathize with a drug dealer who collects ecstasy pills with the intention of selling them onto other drug dealers or users. Is there a way to put her into a corner that gives her no choice but to get the drugs and sell them as a lesser of two evils? Or exploit the fact she is an innocent geek that doesn’t know what the pills are.

Hope this helps.
