Just like in any other sport, there are boundaries around the field. However, if the disc flies past the boundaries, it is not necessarily out of bounds yet. Quality players curve the disc out of bounds and back in and, if caught in bounds, is still considered in and good. If a player jumps from in bounds and catches and throws the disc in play, before he hits the ground, that is considered in and good (this is commonly known as "the greatest" due to its difficulty to accomplish). Once the disc hits the ground out of play or a player catches the disc out of bounds, it is considered a dead disc.
Also recognize that if the disc hits the ground, in the field or past the boundaries, it is a turnover and the other team picks up the disc.
