Marco is a timid teen who has yet to discover his own agency. Over his summer break, he signs up for a lifeguard training course, where he becomes entranced by his polar opposite, Xavier; a boy of mystery and unknown sexuality. Not wanting to risk making a fool of himself or stand out, Marco hides his feelings. When Marco is partnered up with Xavier for CPR and in-water drills, a connection begins to form. As Marco's confidence grows, so does their friendship. When it becomes clear Xavier may feel the same way, Marco must decide whether to act on his feelings or let his queer joy pass him by.
