This is the end of the previous flashback with John Sheppard and his brother. You'll need to run over to the trailer where your dad is drinking on the front step and try to convince him to save your brother. When you have control, run in the direction you're facing down to the blue car, and continue around the chain link fence in a clockwise direction until you run into your dad. He doesn't really care that John's going to drown to death in a drainpipe, so you'll go back and sit with him while he passes away.
