The official trailer for Collide kicks off as couple Casey (Nicholas Hoult) and Juliette (Felicity Jones) decide to have some wintertime fun. They challenge each other to lay down in the snow wearing nothing but their underwear, and agree that whoever gets coldest first and quits has to run around the block naked. It's Casey who can't tough it out, and as he jumps up from the ground blanketed in snow and claiming defeat, he notices Juliette is convulsing and unresponsive.
Things take a sour turn as Casey is informed that a kidney transplant is the only way to nurse Juliette back to health. The catch is that the operation is pricey and beyond either of their means. In order to raise the necessary funds and save Jules, Casey contacts his former employer, drug smuggler Geran (Ben Kingsley), who assigns Casey to a dangerous mission that brings him face-to-face with a powerful gangster (Anthony Hopkins). As the intensity spikes and the pace quickens, Jules is taken hostage, epic car chases play out, shots are fired and Casey's love for his girlfriend is put to the test.
