African Queen

25: She proposes they sink a gunboat. The birth of something new.

45: She sees how he changes when he's drunk so the next day she dumps all of his gin overboard. Now that I'm aware.

60 and -45 (145 - 45 = 60): The story is about their romance and this is when they kiss for the first time. She talks about flowers, he keeps his hand on her shoulder, she touches his hand, and then they kiss. They're no longer just friends. There's no going back now.

-25: All the leeches are off him but the boat gets stuck and he's forced to jump into the water and pull the boat. She helps but they soon realize the boat is stuck in the mud. He tells her he has no regets, she prays to be judged by their love. It rains, the boat continues on and eventually they sink the gunboat. The final turning point.
