A college basketball star jeopardizes his championship hopes as he struggles to rescue his drug-addicted mother while searching for his biological dad.

I have seen quite a few versions of this logline and I was thinking of how to make it work.

As written, your lead has three goals, this is why the logline is having a little trouble.

(1: Save his mother from drugs)

(2: Find his father)

(3: Win a national championship)

but at the same time, your story needs those three goals. That is what the story is about.

As a result, I think you should turn one of those 'goals' into the inciting incident.

-----

1: His mother's overdose causes her to confess to the lead that his father is still alive. (Inciting incident)

2: This sets the story into motions: The lead characters search for his father. (Goal)

3: His search might endanger his chances of winning a national championship. (Stakes)

-----

Possible twist: Maybe his father is someone he knows, maybe a fan of his basketball team.
