Sam and Steve are looking for Bucky, who shows up at their motel, but is still on a mission to kill Steve. Sam shoots Bucky with a tranquilliser dart.
They then flee to a cabin in the woods, where things get very exciting!
Don’t want to post too much more plot in case of spoilers, but they borrowed a car from Sam’s friend Tessa, if that helps. (Can post more plot if this isn’t recognisable.)
I think it ended with the promise of an imminent sequel.
